Two things:

1. Why hwclock? AFAIK programs don't even have permission to read
   the hardware clock by default. It's the system clock (read/set with
   date) that matters.

2. If you set the hardware/system clock to UTC then programs will
   probably use the UTC value instead of local time. And timezone and
   DST should just work, you don't have to reset the clock.

There are two problems with point 2 though:

a) Windows doesn't support hardware clock in UTC so it doesn't work in
   multiboot setups.

b) Some countries use unpredictable algorithms to decide when DST
   begins and ends so the timezone data might not be up to date,
   especially in sarge.
