Linux (and Unix in general) and PostgreSQL both store times in UTC,
which is independent of timezones and DST. The C library translates
UTC into a local printable time, taking timezone and DST into account
as needed. So things "just work" and you don't usually have to do
anything special for the DST changeover.

The first was Texas medicine--the second was just railroad gin,

Now people just get uglier, and I got no sense of time... --Dylan
