=== Added in 3.nn?.0 ===
This new field makes it easier to work out a time in UTC, and identifies uniquely those lines created during a switch from Daylight Saving Time to Winter time, that would otherwise have duplicate times for an hour at time-zone changeover.
The following change was initially planned for release of MX 3.9.0 (b3095), but this section has been amended as the introduction of this new field has been postponed, because of implications of other changes planned at same time (see below table).
The developer has said it is still his plan to add this field during a major release in 2022, but he cannot yet say when it will actually be available to public.
