No, it's (roughly) string -> struct tm -> time_t (mutt_parse_date() ->
mutt_mktime()). It depends on how large time_t is (32/64 bit) whether
there's an overflow or not. For 32 bit values, the problem is known and
should be fixed in C library rather using workarounds in mutt by turning
time_t into 64 bit int.
