The structure contains the time since the epoch in seconds, up to 1000
milliseconds of more-precise interval, the local timezone (measured in
minutes of time westward from Greenwich), and a flag that, if nonzero,
indicates that Daylight Saving time applies locally during the appro-
priate part of the year.
