Namely the thirteenth of December 1901, 12:45:52, Pacific Time.
All dates later than this passed in format "yyyy-mm-dd hh:mm:ss" to the
strtotime function return the correct unix timestamp value (as can be
verified by passing it back to date()).
If a date earlier than 1901-12-13 12:45:52 is used, it returns an error.
I tried this for a while to find the exact cut-off point, and this is it.
Any reason - possibly a limitation of the integer value that is used? I
didn't find this documented anywhere...

Whoops, I should have checked more closely. In fact this *is* documented
as the minimal value of most dates due to the length of the 32-bit integer.
I never considered that these "Y2K" problems work backwards, too...

The upper end of this range is coming up as well, in the middle of
February, 2038.
