Daylight Saving DST 2007

In response to Microsoft's $4k fee to businesses for DST fix, while having this free validation-free fix from microsoft (http://support.microsoft.com/dst2007) vs validation-required update also from microsoft for XP SP2,

Slashdot.org, OmnipotentEntity posted yet another savvy fix, straight to the source, the regedit:

   " $4K? How about this?

Open up regedit and go to the following location:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Contr
ol/TimeZoneInformation


Change DaylightStart to the following
00 00 03 00 02 00 02 00 00 00 00 00 00 00
(Simply we're changing 04 to 03 and 01 to 02)

Change StandardStart to the following
00 00 0b 00 01 00 02 00 00 00 00 00 00 00
(Simply we're changing 0a to 0b and 05 to 01)

Why those changes?

DaylightStart rules:
04 becomes 03 because we're going from "April" (04) to "March" (03). 01 becomes 02 because we're going from the 1st Sunday (in April) to the 2nd Sunday (in March).

StandardStart rules:
0a becomes 0b because we're going from "October" (0a) to "November" (0b). 05 becomes 01 because we're going from the Last Sunday (in October) to the 1st Sunday (in November).

Consider that one on the house. It works for Windows 2000 at least.
