Nope, the NTP protocol uses GMT (or UTC, if you prefer that name)  
exclusively.

However, once you've updated the timezone files, you either need to  
restart all of the processes which have cached the old TZ file info,  
or simply reboot.  You might find running "ntpdate -b" to reset your  
clock once before starting ntpd will help correctly sync if your  
local clock is one hour off (depends on whether your BIOS is trying  
to keep local time or GMT time)...see "man adjkerntz".
