NET$DISABLE_DTSS works (at least on other platforms).

Regarding DST changes, SYSGEN parameter AUTO_DLIGHT_SAV is still around 
and works.

If you prefer DTSS I'm using NTP as a DTSS time provider on Alpha and 
Integrity systems. SYS$EXAMPLES has a DTSS subdirectory on these 
platforms containing DTSS$PROVIDER_NTP.C which I modified slightly 
(iirc). Need to dig around for details and two DCL procedures to start 
it at system startup. Did not try it on x86 yet.

Hope this helps,
Hans.
