Western Argentina Summer Time (WARST) is 3 hours behind the prime meridian all year.
There is a dummy fall-back transition on December 31 at 25:00 daylight saving time (i.e., 24:00
standard time, equivalent to January 1 at 00:00 standard time), and a simultaneous spring-
forward transition on January 1 at 00:00 standard time, so daylight saving time is in effect all
year and the initial WART is a placeholder.
The format is TZ = local_timezone,date/time,date/time.
Here, date is in the Mm.n.d format, where:
Mm (1-12) for 12 months
n (1-5) 1 for the first week and 5 for the last week in the month
d (0-6) 0 for Sunday and 6 for Saturday
