There seems to be some confusion about patching esx2 for the US 2007 DST changes?

Here is VMware’s KB on the subject.

So how do I determine when DST starts and ends on my box? Seems like a logical question. Try This command…

zdump -v /etc/localtime | grep 2007

Disclaimer – I still need to confirm this is the definitive answer by rolling the date on a test box forward.

You want to see Daylight Savings Time start on March 11 and end on November 4.

/etc/localtime  Sun Mar 11 07:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 CST isdst=0 gmtoff=-21600
/etc/localtime  Sun Mar 11 08:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 CDT isdst=1 gmtoff=-18000
/etc/localtime  Sun Nov  4 06:59:59 2007 UTC = Sun Nov  4 01:59:59 2007 CDT isdst=1 gmtoff=-18000
/etc/localtime  Sun Nov  4 07:00:00 2007 UTC = Sun Nov  4 01:00:00 2007 CST isdst=0 gmtoff=-21600

Here is an old box that hasn’t been patched yet.

/etc/localtime  Sun Apr  1 07:59:59 2007 UTC = Sun Apr  1 01:59:59 2007 CST isdst=0 gmtoff=-21600
/etc/localtime  Sun Apr  1 08:00:00 2007 UTC = Sun Apr  1 03:00:00 2007 CDT isdst=1 gmtoff=-18000
/etc/localtime  Sun Oct 28 06:59:59 2007 UTC = Sun Oct 28 01:59:59 2007 CDT isdst=1 gmtoff=-18000
/etc/localtime  Sun Oct 28 07:00:00 2007 UTC = Sun Oct 28 01:00:00 2007 CST isdst=0 gmtoff=-21600
