These are highly complicated, and so have been left until after the simpler ones!


===Use of spaces===


===Where date format codes are used===
There are multiple parameters for specifying dates and times, and you might want spaces to appear in that output format.


Time/Date format codes are used in two places:
If we need to include spaces, then we have to enclose the whole specifier in double quotation marks e.g. <code><#tag_name format="x y z"></code>
# As part of report names for NOAA style reports (see [[Reports_folder#Additional_Information_for_NOAA_reports|this page]] for full details)
# As part of web-tags that report either times or dates, or report both a date and a time (this is what the rest of this page covers)


===Which web tag names take date/time output formatting modifiers===
Any literals (i.e. characters we do not want to be interpreted by the date time parameter parser) are generally enclosed in single quotation marks, within the double quotation marks delimiting the specifier. 


Cumulus includes a lot of web tags that can output dates, times, or both.  In many cases, it will not be obvious from the web tag name whether it can return both time and date information.  Sometimes, the default (without any output format modification codes) will reveal whether date and time information are both available, but unfortunately that does not always work.  The following table shows some examples of which web tags will accept time and/or date output modifiers.  '''Be aware''', some of the tags shown in the table may return "---" or "--:--" or some other non-numerical output  in two circumstances:
This can cause you a problem if you want to use a date/time specification in a script because the script wants literal delimiters round the entire web tag, so that delimiters remain when the web tag itself has been processed into a string by Cumulus.  The complicated sounding (but actually simple solution) is to avoid placing literals within any output format specifier, but instead put the literals outside with separate web tags before and after each literal. Then you can use single quotes outside.  This is employed in some of the scripts at  
#where the event they report does not happen that day (e.g. moon rise and set do not always happen within a calendar day on Earth.
#where the related data is not defined until at least one whole day has been recorded (e.g. some monthly and yearly web tags do not contain data until second day of month/year)


Remember, the default format for web tags reporting date and/or time is often dependent on the locale you are using for running MX (and we will discover below the effect of some output format modifiers is also dependent on locale):
===Which tag names take date/time output formatting modifiers===


If you run MX on a computer using Microsoft Windows, then the "locale" is determined by settings in either '''Control Panel''' (go to "Clock and Region" screen, choose "Change date, time or number formats", choose "Language preferences") or using "Settings app" (go directly to "Language").
There are nearly a thousand different tag names.  


On computers running other operating systems, the locale is set when you install "Mono-complete".  You can overide the default locale with [[MX_on_Linux#Parameter_for_changing_Locale|-lang]] parameter when starting MX.
There are a few tag names labelled as being fixed format, obviously they cannot take any output modifiers.


Time modifiers can be used to change the way that durations are reported, for tag names that report durations instead of clock times. Examples include '''<#daylength>'''  and '''<#MonthDailyRainHD format=H:mm>'''.  The [[webtags]] page clearly identifies those tag names that report clock times, but it is left to you to work out where durations are reported.
There are some tag names (e.g. moon rise) that relate to an event that does not happen each Earth day, so those tags have to be able to report "--:--", and you cannot modify their output.
There are some tags (e.g. highest temperature range in month/year), for which Cumulus has been coded to report "--:--" on the first day of that period (because there is only a partial day to consider you might not yet have experienced a true maximum and a true minimum, so modifying their output can only be done on subsequent days.
It is not possible here to list each of these tag names, and indicate which time/date modifiers are accepted on a tag by tag basis.  I did consider adding a column for that purpose to each table on the [[webtags]] page, but decided those were complicated enough.  Instead, the following table, explains much more simply, which web tags will accept time and/or date output modifiers:

^ Note: There are some monthly/yearly web tags (e.g wettest day) where a date tag is available (i.e. <#MonthDailyRainHD>), but not a time tag.  You may get a time back if you put output time parameters into such a date tag, but the time returned may be wrong (especially if you don't use midnight rollover, for that wettest day example <#MonthDailyRainHD format=H:mm> it does return a time when the rain stopped, but the hour is out by 9 or 10 hours on a 9 or 10 am rollover).
^ For the monthly and yearly web tags, the date and time are in separate tag names. It is not possible to get both time and date out of either tag name.
 
Note: There are some monthly/yearly web tags (e.g wettest day) where a date tag is available (i.e. <#MonthDailyRainHD>), but there is no time tag.  As explained before, in that wettest day example '''<#MonthDailyRainHD format=H:mm>''' returns the duration in hours and minutes since rollover for which rain continued to increase on that date, not the clock time. For rainfall, only '''<#LastRainTip>''' can have output modifiers added to report a clock time.
 
===Locales===
 
The default format for many tag names reporting date and/or time is dependent on the locale you are using for running Cumulus (1 or MX).
 
The effect of some output format modifiers is also dependent on locale.


===What can time/date output modifiers do?===
For MX running on most operating systems (and therefore using Mono),  type <code>locale</code> to see the default locale that will be adopted when mono-complete is installed as MX will, by default, take locale setting from Mono. When you start MX, you can ask it to use a different locale to that picked up by Mono, by adding the parameter "-lang locale-code", see examples at [[MX_on_Linux#Parameter_for_changing_Locale]].  For example, the Australian English language with UTF-8 encoding locale is defined as: en_AU.UTF-8.


These output format modifiers allow you to override the default display format for a particular web tag (subject to restrictions seen in last sub-section),
The available locales on your computer in Linux are listed by <code>locale -a</code>. For example, the Russian locale would be selected as the one your computer uses ''for the current session only'' by using <code>LANG=ru_RU.utf8</code> either typed into a terminal session before you start MX, or used as a parameter (preceded by "-") as you start MX interactively.
using the format specifiers to be described later. The characters used to represent year, month, day, hour, minute, second, microsecond, and am/pm; all differ between C1 and MX.  


#You can choose whether 12-hour clock is used with am/pm, or the 24-hour clock is used.
For permanently changing the locale used by your system, the instructions vary considerably according to the kernel used in your operating system, so you need to look up the instructions for yourself. However, if you have a graphical user interface, such as the full Raspberry Pi Operating System provides, you might have a configuration command in terminal mode and a configuration app accessed (within ''Preferences'') from the "Raspberry" key on the official keyboard.  For the Raspberry Pi, please read [[Raspberry Pi computer page]] for more details.
#You can choose to include/exclude leading zero for hours.
#You can only report the hour if you don't care about the minutes, or only report the minutes if you don't need the hour.
#In most cases you can add seconds to the output, and in some cases either milliseconds or microseconds.  
#* This does not imply that Cumulus calculates everything every microsecond, in fact for the legacy software many derivatives are only calculated once a minute, but the flexibility is there for time outputs.
#* It is also worth remembering that if the required derivative relates to a period when Cumulus was in catch-up ('''reading archive data''' is how MX describes it), then the time-stamp resolution is restricted by the station's logging interval, even if that is only every half an hour!


===Use of double quotation marks===
For Microsoft Windows Operating Systems, a Language is defined within the "Region" page of the Settings app. That should be sufficient for the legacy software that uses Delphi.


The general syntax is <code><#tag_name format=x></code> where '''x''' can represent a single chacter, or multiple characters without any spaces.
However for MX date and time formats within Windows Operating System, you must use the older '''Control Panel''' (go to "Clock and Region" screen, choose "Change date, time or number formats", choose "Language preferences") because it is only there that you can adjust all the defaults used by .NET.


If we need to include spaces, then we have to add double quotation matrks round the right hand side as shown here <code><#tag_name format="x y z"></code>
===Time zones===
 
Before I explain what time/date output modifiers can do, something they can't do.
 
All web tag outputs are in local time, except '''<#timeUTC>'''.
 
Although Cumulus 2 internally stored all date/times in UTC, no flavour of Cumulus is currently able to output the time-stamp for any weather extreme in UTC, if your current time is not in UTC.
 
However, for MX only, you can use a script to convert a time to UTC. This is not the place to tell you how to write the script, but taking time of highest pressure today as an example, you would use <#TpressTH format=Hh:mm> and <#TpressTH format=zzz>, the first gives hours and minutes in your local time, and the second gives the offset that needs to be applied to that time to convert it to UTC.
 
===Time resolution===
 
For the legacy software, there may be no point in asking for seconds, as Cumulus 1 did some actions at one minute intervals.
 
If Cumulus obtained archive data, as part of the catch-up process it can do when it restarts, any time-stamps for that period can only be the time of a particular archive record, so that might be every half an hour, but not aligned precisely with hour changes.


===Dependency on Cumulus flavour===

There are differences between the original (legacy) Cumulus and MX.  The characters used for specifying the required output modification vary, so all tables showing details of time and date modifiers have separate columns showing what is used in each flavour.

===Effect of Locales===
Locales have already been mentioned twice on this page, now it is time to say what is defined in these locales.


====Date formats====
====Date formats====


Cumulus works with dates specified in either a day before month before year format, or ISO 8601 date format where year comes first (yyyy-MM-dd).  If you are in the USA, Cumulus will not use your month first date internally, but you can see your preferred format in any output as you can can combine the month specifier, with the day specifier, in that order, to get an output where the month appears first (see example in table below). <big>Please could an American contributor please check if the "M" modifier works for them and update the table below</big>.
Cumulus works with dates specified in either a day before month before year format, or ISO 8601 date format where year comes first (yyyy-MM-dd).
 
Locales will define a '''Short Date Format''' and a '''Long Date Format'''.  Which date format is used as the default, depends on which web tag is used. What appears in short and long formats depends entirely on the selected locale. 
 
If you run MX on a computer using Microsoft Windows, then the "locale" is determined by settings in the (now hidden) '''Control Panel''' (go to "Clock and Region" screen, choose "Change date, time or number formats", and enter the formats you want for long and short here).
 
 
On computers running other operating systems, the locale is set when you install "Mono-complete". That is determined by language settings when you set up your computer, but you may be able to edit the configuration to change what is defined for the long and short formats. You can overide the default locale with [[MX_on_Linux#Parameter_for_changing_Locale|-lang]] parameter when starting MX.


There is a single character output format modifier ('''G''' or '''c''') that makes the output appear exactly as defined in short date format, followed by long time format. There are other format codes in table below for other date outputs.
If you are in the USA, Cumulus will not use your month first date internally, but you can see your preferred format in any output as you can can combine the month specifier, with the day specifier, in that order, to get an output where the month appears first (see example in table below). <big>Please could an American contributor please check if the "M" modifier works for them and update the table below</big>.


[[#Locales]] will define a '''Short Date Format''' and a '''Long Date Format'''. You will see references to those in the table below explaining available output format modifiers, for example the single character output format modifier ('''G''' or '''c''') listed at the start.
