Stay out of the timezone mess altogether.
1. Keep times in UTC.
2. Let the manager's preferences have a local time zone
for himself, and when he enters a time you translate from his local
timezone to gmt.
3. Maybe add a system configuration parameter to display the timezone
in which the times should be displayed.
That's basically the way UNIX handles this, and in a way that's
why it's probably the easiest aproach (functions to translate to
local time zones and back already exist in the standard C library).
BTW - the term local NTP server hints to me that you might not be
aware what that means - NTP servers give GMT time. They don't care
about local time zones. The only place where the local time raises
it's ugly head (or should be) are the functions which actually print
times (to logs or on the screen), everywere else you should be able to
take a large integer number anywere in the world and treat it as the
number of seconds since 12AM, Jan 1, 1970, GMT.

Hi All
I'm building an E-commerce auction store for Hungarian company.
When the manager add new sale He set the expiry date/time of the auction (
gmt +1 - hungarian ).
My server is located in Israel and is tuned against local NTP server.
How can I insure that my system will behave correctly considering the time
zone/saving light ?
