I need to calculate the number of days between two dates. Sounds easy... I could just use the strtotime function and go from there. BUT the problem is that some of my dates are all the way back to the 1940s. strtotime() does not handle dates prior to 1970 (the unix epoch).
Sooo... how can I go about this calculation? I'm assuming I'll have to write my own function for it?
Thanks,
Mark
