hey, jim, thanks for reply. I am not sure 64bit executable is what I want since I am using a 32 bit machine

I experienced a lots of error while using gnu c library time.h functions, where time_t type variable is used a lot. Wierd enough, say in my main() I get a time_t tim=1230768000 returned by localtime(). And I pass it to a function A(time_t tim). Inside the A() I see tim become negative value!!!
Hopefully I expressed the problem clearly
