I think you're talking about the hardware clock, which isn't really
relevant.  It's only used to set the system time when the machine
boots, and then it is typically ignored.  The system time is the
clock used by linux while running, and is by definition the number of
seconds since 00:00:00 January 1, 1970 UTC, independent of timezone,
daylight savings time, etc.  So this shouldn't be affected by the
DST switch.
