Preventing DST time problems?

I am running on a dual-boot system running Window2000/Solaris 10....The
last Daylight Savings Time change that we had this month just made my
clocks change erratically...I would like to ask, if whats the best Time
settings for both operating systems (windows and solaris) in order to
prevent drastic erratic time changes during DST changes??

Here are my current clock or time settings:

1. RTC or the Hardware Clock is set to UTC..(The BIOS is set to UTC)

2. Solaris DISPLAYED Time or TZ is set to TZ=UTC....and ZONE INFO is
set to UTC also...

3. Windows, is set to show local time zone....but, were it says under
the Time Zone properties, I have the "Adjust clock to DST
Automatically" UNCHECKED at the moment.

Now, #1 and in #2 I do want to leave were its at, in other words, I
want Solaris to keep its time in TZ=UTC and also the "Zone Info as UTC
also. Thats fine.

Now, in order to prevent problems or erratic time changes during the
DST changes, what should I do under Windows?? In other words, should I
leave the settings above were its at...Or, I do need to change some
things around to prevent possible issues during DST changes in a
dual-boot Windows/UNIX system?

Thanks in advance for the help!
