Hi all,

I need to update client machines with the correct time if it is inaccurate.
The server I'm using will always have the correct time so I'll be using that
as the source of correct time. The code below works most of the time but is
an an hour off sometimes (daylightsavings time).

For example, If I change the date on a local to machine to Jan 2005, my code
will update the time an hour ahead of where it should be. Any help would be
appreciated.

Thanks,Paul

Code is below
