Griping About Time Zones

Daylight savings is ending in two weeks and I'm going to gripe about it. Not
the usual gripe about people having to adjust their clocks and schedules (I
for one, actually like daylight savings), but about how basically everyone
writes time zones incorrectly. When people give a time with a time zone, such
as "five o'clock in San Francisco", many people just write "5 PDT" or "5 PST"
without giving a thought where that "D" or "S" come from. Well, those
acronyms stand for "Daylight" and "Standard," respectively, so you should only
use "PDT" to refer to times in the summer, and "PST" refer to times in the
winter. If you want to be generic, you can use "PT" for everything and let
context take care of the exact time zone.
