DST: The Gift that Keeps on Giving

The new North American Daylight Savings Time rules are a lot like the message in Repo Man: the life of migrating calendar servers is aways intense.

Here's the thing to keep in mind: If you're going into Exchange 2003 -- make sure you've applied patches for the new DST shifts.

EHLO has this good posting on the subject: Exchange 2003 and DST fix.

Exchange 2007 automatically has the DST shift dealt with.

Now there are some vendors out there who tell you that as long as you're in the same time zone you're covered, you don't need to upgrade Meeting Maker or Oracle Calendar Server. That's true -- until you migrate.

We can handle re-basing the events in either of these to make them work if necessary. Please just be on the lookout in your test lab for meetings and appointments off an hour in the "DST Delta" in March and November.

As always, it is much easier to deal with these if we find them early.
