Yes, do the daylight saving time decision in a utility which calls
settimeofday() to set the timezone information appropriately. This could
be called from cron on the days when the changes occur (in England this
is the subject of annual legislation and hence not suitable to compile in);
the current value can be saved for the same utility to read and set on
reboot. The current ctime() scheme seems to make very poor use of the
flexibility provided by the timezone info in {gs}ettimeofday().
