[COLUG] Linux and UTC

Internally,  yes.  And notably,  file time stamps are in UTC.
(May very with the FS driver.  Certainly EXT2 stores times in UTC.)

The PC hardware clock may still be set to local time.
But when the system is up and running,  internal time is UTC.

With Linux,  the file /etc/localtime is either a sym-link to
(my preference)  or a copy of  (how SuSE does it)  the correct
zone offset info file from /usr/share/zoneinfo.
