Time servers all speak UTC (Coordinated Universal Time, nee
Greenwich Mean Time) so they don't care about local variances
in daylight saving rules.

I can't find a reference now, but I recall that in Australia, each

for DST for the following year *in that state*.  They apparently don't
do that anymore.  Here's a summary from the Bureau of Meteorology.
