Has anyone yet come up with a solution on changing older SCO OpenServer
5.0.4 / 5.0.5 / 5.0.6 systems to accommodate the new daylight savings
dates starting this year??

I have looked around at SCO's site and they have an update to install
on 5.0.7 systems that also indicate you should install new libc, etc

Anyone know how to fix this on older SCO OpenServer releases??

Thanks for any help

I'm in the EST timezone, and so I would edit /etc/TIMEZONE

from: TZ=EST5EDT
to: TZ=EST5EDT,M3,2,0/2,M11,1,0/2

I just tested this on an old 5.0.0 system by setting /etc/TIMEZONE
to TZ='CST6CDT5,M1.4.1/2:00:00,M11.1.0/2:00:00' at 1:00 on 1/22
To set January 22 as the conversion date. What happened: At 2:01
CST the DATE command returned Mon Jan 22 03:02:45 CDT 2007.

The RTC was also updated by the root cron entry:

1 3 * * * /etc/setclk -rd1800 > /dev/null 2>& that runs at 3:01am and
says "if the offset is larger that 1800 seconds, reset the RTC"

So on 5.0.0, the above /etc/TIMEZONE setting effected a change from
CST to CDT and updated the RTC for the change. Other people have reported
that the TIMEZONE string works on 5.0.2 and 5.0.4 as well.

You should plan on a reboot sometime before March to make sure that
"init" and all other processes are aware of the changed time zone
information. For example, Bourne shell users get the boot-time TZ
string by default.

Thank you, yes, punctuation does matter!
