Y2K7: Daylight Savings Time Changes and OpenSolaris
05 Mar '07 - 03:22 by benrAs everyone should know by now, Daylight Savings Time has been moved this year to the second Sunday of March: March 11th. (Can you believe its March already?) Naturally anyone on OpenSolaris will want to know whether or not to worry. The quick answer is: if your on Nevada Build 31 or newer your OK.
The more verbose answer is that the original BugID's for our upcoming change are:
Both these changes were integrated into snv_31. Other updates have occurred as recently as snv_57 (6512648) which predominantly addressed "Bahamas adopts 2007 US DST dates".
If your like me (paranoid) and don't want to trust someone elses word for it, Lloyd Staley shared an awesome tip on the OS-Discuss " Y2K7 update?" thread. You can use zdump to dump the zoneinfo and see when DST begins and ends:
# zdump -v US/Pacific | grep 2007 US/Pacific Mon Mar 5 07:56:41 2007 UTC = Sun Mar 4 23:56:41 2007 PST isdst=0 US/Pacific Sun Mar 11 09:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 PST isdst=0 US/Pacific Sun Mar 11 10:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 PDT isdst=1 US/Pacific Sun Nov 4 08:59:59 2007 UTC = Sun Nov 4 01:59:59 2007 PDT isdst=1 US/Pacific Sun Nov 4 09:00:00 2007 UTC = Sun Nov 4 01:00:00 2007 PST isdst=0
Mega-props to Lloyd. That was a command I was unaware of but definitely calms my nerves, and hopefully yours as well.
Well, there are even some of us still running SunOS boxes (choke). I wrote a quick little script to update all the zoneinfo files for my Linux, Solaris and SunOS systems. Easier than getting all the stinkin’ patches for all the different versions I have running.

did you update your glibc on Redhat 8?...
you might want to get the source rpm and check out the timezone directory in the glibc tarball…glibc_badness - 09 March '07 - 23:17
I hate, hate, hate the time change. I don’t know why we can’t just leave it alone. We are right now having light in the morning and in the evening. LEAVE IT ALONE11111dhouda (Email) - 10 March '07 - 19:05

P90x .It really is not expensive if you factor in the cost
of a gym membership,P90x workout . The cost for P90X is
about three months of a paid gym membership but you get to
keep the program foreverP90x . You can try many of the
online sites, but it will be the same as buying from the
company or a Beachbody Coach. Make sure you are getting
original DVD’s. People are selling copies all over. The
problem is how long will they last, P90x workout ,and you
truly need the exercise and nutrition guide to even follow
the program. You can go to any site or you can go to
[[http://www.p90xmall.com]] and click on products. P90x dvd You can
order directly from the site,P90x dvd.p90x (Email) (URL) - 05 May '10 - 05:41
