After the change from Daylight Saving Time to Standard Time, the times for
all Microsoft Exchange Server scheduled events move ahead by an hour.
Similarly, after changing from Standard Time to Daylight Saving Time, all
Microsoft Exchange Server scheduled events move back by an hour.

The above behavior will be noticed if the Windows NT Server is set to
automatically adjust for Daylight Saving Time.
This is by design. All objects in the system are based around Greenwich
Mean Time (GMT) plus or minus the difference of the server's time zone from
GMT. GMT does not change with the Daylight Saving adjustment and this
causes a shift in the times of the scheduled events.
One workaround is to turn off the Automatically Adjust for Daylight Saving
Time option in the Date/Time applet under the Windows NT Server Control
Panel. After the Daylight Saving time change, manually change the system
clock twice a year.
