Hello, I'm new here, I have 2 sites that are running SCO 7.1.1 and to allow for the new DST I have entered this in the /etc/TIMEZONE file, the following TZ info: TZ=AST4ADT,M3.2.0/2:00,M11.1.0/2:00 export TZ. This is the new DST info to compley with the new date change. I used this method because I could not find a patch from SCO for this older OS. This worked fine on 95% of the sites. What I found was when April 1st rolled by the clocks on 2 sites jumped ahead by an extra hour. I checked xntpd log and found it failed due to the fact the drift was to big. So, I have to assume that the DST kicked in again. I also checked the CRON and it looked ok, checked /etc/rc2.d S97ntp, it's ok, also checked S10dst and it was ok. Checked ntp.conf and it was ok. Not sure were else to look.
