Linux is really good for time zone calcuations, because it tends to come with a
complete list of time zone info, including Daylight Savings transitions, and a
simple

TZ=<new time zone>

can do a lot of conversions.  I use a similar trick on my IRLP node to schedule
connections to nets that are scheduled in some other time zone.  The script is
called

tzschedule [week] <time zone> <hour>  <command> [parameters]

[week] is the week of the month.  This triggers extra logic for schedules that
are like "second Tuesday of the month", since cron doesn't handle this well.

<time zone> is the name of the time zone to schedule the event in, eg UTC

<hour> is the hour of the event in the foreign time zone.

<command> [parameters] is the commandline to run

This script is designed to be called from cron. :)

Cool. :)
