Do Vista recognize that Daylight savings time has been moved up this year

[Mark S]

Does anyone know if Vista (XP pro and Business Server 2003) will recognize
the earlier daylight time if I have been updating my machines regularly. All
my machines are set to automatic update from Microsoft.

Vista should be ready out of the box. XP Pro SP2 and Server 2003 had a
patch released in December (KB928388) which has been superseded by a
February cumulative time zone update (KB931836). If you have them
installed, you should be fine. XP SP1 and previous operating systems
will not have a patch released, but MS provides instructions on how to
update the system manually with a .reg file, .vbs script and a .cmd file
(http://support.microsoft.com/kb/914387/en-us).

Hmm? Am I missing something? Can't you solve the problem by simply
resetting your clock? If so why bother with the Registry?

Certainly, you can do that. Without the patch, you are missing a couple
of nice features, and could encounter a couple of minor annoyances.

Feature #1: The ability for Windows to handle Daylight Saving Time for
you automatically on the correct dates.

Feature #2: Time synchronization with an NNTP server. Since NNTP
servers always serve up GMT, if Windows thinks it is at a different
offset from GMT because you are between the new & old dates, time
synchronization won't work properly.

Minor annoyance #1: Windows uses the current offset from GMT to report
time stamps on files across the network, so if your DST settings aren't
correct, time stamps for files across the network are off. Not a
problem for most people, but for those that need them to be reasonably
accurate it can be a pain.

Minor annoyance #2: Related to #1, Windows uses Dynamic DST to report
the time stamps of files based on the DST settings in effect on the date
that the file was time stamped. If you don't have the new registry
fixes, you can again get inaccurate time stamps reported for your files.
