| Can anyone tell me why this script is not working? It's my Daylight
Saving workaround for my Solaris 6 server. For some reason it doesn't
change the time. Basically, at 03:01 it's suppossed to change the
time to 02:01 but it doesn't do anything. Any suggestions would be
apprecieated.

I don't know why the script fails (maybe you have NTP which
automatically corrects the time), but changing the system clock to
adjust for daylight saving time is wrong. You need to modify the
timezone database. Perhaps sun.com has a timezone fix that you can
download, unless they have stopped supporting Solaris 6.

Not answering your question, but aren't you setting yourself up for an
"infinite loop" of time zone resets? That 3:01 cron event is going to
trigger every hour if you push the system clock back.
You have to delete the script, change the crontab, or set some flag to
indicate that you've already reset the clock.
Or perhaps "Groundhog Day" is your favourite movie ;)

My Solaris servers are currently at these kernel levels. What do I
need to check to see if I'm ready for the new DST changes for 2007?
Solaris 8 108528-15
Solaris 9 118558-38
Solaris 10 118833-24
Thank you.
