If you change the time and do not change the offset from UTC then any times in
your system will be incorrect for some period of time.  This year if you use
last years TZ parameters your time will be wrong for three weeks this spring
and for one week this fall because the wrong offset will be used.  For a lot of
people this will not be noticed.  If you are on a mailing list where some
person has taken it upon themselves to act as the "time police" you will hear
about it.

If you need the time to be converted to UTC then you need to know what the
offset from UTC is and when the change takes place otherwise you don't know
what time it is.  I send firewall logs to dshield.org so the date/time stamp
must be correct.
