What is time_t ultimately a typedef to?

Question

I searched my Linux box and saw this typedef:

typedef __time_t time_t;

But I could not find the __time_t definition.

Under Visual Studio 2008, it defaults to an __int64 unless you define _USE_32BIT_TIME_T. You're better off just pretending that you don't know what it's defined as, since it can (and will) change from platform to platform.
