ntp knows nothing about time zones. It gets the remote time in UTC. time
zone info is all handled by your local machine. On unix/linux/.. (sensible
machnes) the machine time is ALWAYS UTC. time routines do the translation
using a file called /etc/localtime. On windows it is more difficult, since
Microsoft has never heard of timezones, so you have to kludge it yourself. 
Exactly how your machine or your implimentation of ntp kludges it I do not
