No. NTP does not concern itself with time zones or issues of daylight
vs. standard time! NTP deals ONLY in UTC! Displaying local time is the
responsibility of the Operating System. You generally have to configure
something in the O/S to tell it what time zone you wish to use for the
display of time and what the current rules for changing from standard to
DST and back are.
(from the man page for date)
" -u Display (or set) the date in Greenwich Mean Time
(GMT-universal time), bypassing the normal conversion
to (or from) local time."
A single machine might display different times for users in different
time zones!
