# RT#57800 (GH#3): str2time fails on numeric m/d/yyyy dates before 1970
# str2time('5/1/1960') was returning undef with "Day too big" errors on
# 32-bit systems. Root cause: strptime extracts the 2-digit year (60) and
# stores century (19) separately. str2time must reconstruct the full 4-digit
# year before calling Time::Local to avoid the 2-digit year windowing heuristic
# mapping year 60 to 2060 instead of 1960.
