New DST Comes Into Effect This Weekend

Just a quick reminder to let you know that the new daylight saving times come into effect in the US, Canada and Western Australia this weekend.

If you're running Solaris 8, 9 or 10, head on over to Sunsolve and update your patches. If you're running Solaris 2.5.1, 2.6 or 7, best get onto the phone to your local support centre as the patches for these releases are gonna cost you (cos these OS's are way past their EOSL).

If you're running OpenSolaris, then provided you're running build 31 or later, you'll be OK, that is unless you're in the Bahamas (I wish) in which case you'll need build 57 or later. If not, upgrade. Anyway, if you're playing with cutting edge software, why aren't you taking advantage of all the cool new features?

And for the paranoid, you can check if your host will adjust it's representation of the time correctly by running zdump(1M) against your timezone (ignore the 1st line - this is when you ran the command):

[devon:~] $ zdump -v US/Pacific | grep 2007
US/Pacific Tue Mar 6 10:20:17 2007 UTC = Tue Mar 6 02:20:17 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
[devon:~] $

And don't forget your other operating systems. Whilst we'd all like to think there's only Solaris, other lesser ;-) operating systems do exist.
