This is one of those regularly annoying questions we get in NTP even
though NTP only knows about UTC.

All O/S vendors have patches/updates available for their flavor of O/S's
to get the displayed date match the local time in your area. For Unixs
it's just an update timezone file that needs to be copied to the right
locations within the filesystem. With Microsoft it's a Windows update I
think to the registry settings. For all other O/S's they will have fixes.
