32bit vs 64bit - 32bit can't handle 2100 in strtotime?

Not if that "simple" date conversion uses the system time_t functions
(which most of the common functions do).  If you need to handle dates
outside the range of 1970-2038, you'll need to use alternate functions
that can handle the expected date range (and I don't know if such exist
in PHP; you may have to code them yourself).

Portable code should not assume system date routines can handle dates
outside 1970-2038; you shouldn't depend on 64 bit systems having larger
time_t (I don't think they all do).

I don't speak for anybody but myself - that's enough trouble.
