ColdFusion and U.S. Daylight Saving Time changes in 2007

In the US for 2007, the US Energy Policy Act of 2005 moves DST observances from the second Sunday in March until the first Sunday in November. "Studies" will apparently determine if this remains permanent, but if you're running applications on ColdFusion MX 6.1 or ColdFusion MX 7.x, you'll want to be on Sun's 1.4.2_11 (or later VM.)

More info on DST here http://en.wikipedia.org/wiki/Daylight_saving_time

And here's the skinny on the world-wide implementation of DST in each country/region of the world (and a bit of dark comic relief...)

To wit:

"On September 5, 1999, terrorists were transporting a bomb that they mistakenly thought was set to go off at 5:30 PM Israel Standard Time; it was actually set for 5:30 PM Palestinian Daylight Time, which was an hour ahead. As a result, the bomb went off while the bomb was still being transported, killing the terrorists (and earning them a Darwin Award)."

Anyway, we had an issue to with ColdFusion MX 6.1 on JDK 1.4.2_11 having to do with CFLDAP support and we are issuing a patch for that here in the next day or so:

But in general, for proper handling of the US 2007 DST issue, please read the Adobe Tech Support article here for the latest info:
