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.
