Cause 32 bit system can only handle epoch before 2038 (2**32) if they rely on the unix built in timegm.. The CPU architecture can be 32 bit, as long as a larger size of value is used for times. The code he posted works for me on FreeBSD, on a 32-bit x86 system. Apr 10, 2087 it says. -- We're working on a six-year set of freely redistributable Vacation Bible School materials.	[reply]

Did you try it? WinXP on a 32-bit Pentium 4. Even if the CPU doesn't support 64-bit arithmetic — I don't know whether it does or not — it can still be done by software. Think about it... entire CPUs can be emulated in software. However, I'm guessing the module doesn't use 64-bit arithmetic (hardware or software), but rather floating point numbers. They have 56-bit of precision on my system.	[reply]
