Well, I thought we had addressed all of our issues related to the initial change of Daylight Savings Time (DST) back in 2007. Server and Client operating systems were patched; so were messaging environments and anything supporting Network Time Protocol (NTP) was looked reviewed. It was even necessary to make some changes to systems that synchronize e-mail to mobile handsets such as RIM's BlackBerry Enterprise Server or Motorola's Good Mobile Messaging and patch the handsets themselves.
Preparing for DST three weeks early and one week later seemed almost reminiscent of the buildup to Y2K. We didn't experience too many glitches other than known problems with Outlook calendars and I thought we would be set after making it through 2007. Low and behold, DST part deux has come along and flummoxed quite a few folks.
If you're currently experiencing issues that give you a feeling of "DST Deja Vu", don't dismiss them. Apparently the hotfix for Windows operating systems has been revised twice since it was first released in February 2007 as 931836. The latest patch is 942763 and it can be downloaded here.
If you're running Microsoft Exchange server as your messaging environment, you may want to peruse "Preparing for daylight saving time changes in 2008" article on Microsoft's support site to make sure you haven't missed anything.
