How difficult will it be to add and subtract several hours from my local time, in order to get accurate obtain times elsewhere in the world... such that I will be able to use difftime() to see the difference, be able to set alarms when a certain time zone enters a specific time (hey my friend is now online ;-), alarm_set (+/- offset_to_time_zone); where "offset_to_time_zone" is added/subbed from my local_time, and we simply wait for a count down, or perhaps a match at least... and things like this... Would there already be functions that handle World zones already? Thanks for any advice, comments.... Code snippets always welcomed too.... ;-) email: radsmail AT juno DOT com http://members.tripod.com/~RadSurfer/ Join us on Yahoo at: http://groups.yahoo.com/group/BorlandCPPBuilder for informal discussions about all versions of C++Builder...
