As far as the timestamps in the log are concerned, Cumulus doesn't do anything in particular for DST. It generates timestamps based on the Windows clock. So basically, at the start of DST (i.e. when the clocks 'go forward') you will get an apparent gap of one hour in your data, and similarly at the end of DST (i.e. when the clocks 'go back') you will get an apparent hour of duplicate timestamps. The exact timing of the affected hours depends on the type of station and when Cumulus was running. | As far as the timestamps in the log are concerned, Cumulus doesn't do anything in particular for DST.

==What formula does Cumulus use for Apparent Temperature?== | |||
It uses a formula from the Australian BOM - http://www.bom.gov.au/info/thermal_stress/#atapproximation | |||
