Hi,

there is an integer overflow handling received emails' date, i.e. when

this one's date is `Tue, 19 Jan 2038 11:14:07 +0800', which overflows to
14 Dec 1901. the displayed `Date' field of the email header doesn't change.

i guess the behaviour is:
date_to_int();
sort_mails();
int_to_date(); /* integer overflow */

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.
