Maybe if you want to schedule a meeting for 4pm local time, no matter the time zone. Some countries have very unpredictable daylight saving schedules.
(For example, http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=551195 - "To keep on with the great work our government has done the past two years
of deciding stuff with 2 or 3 days of anticipation, the government has just
decided that we won't switch to DST this Sunday.")
Australia also has some interesting history with daylight savings. I remember it being used for a discussion of DateTimeOffset in .net because it could showcase all the different scenarios.
