Proposed fix for bug #6439 "from_unixtime() function returns wrong datetime
values for too big argument".
Description: On systems where sizeof(time_t)==4 (e.g. Linux x86) MySQL's from_unixtime() function returns wrong datetime value if its argument is too big to fit into 32bits. It should return error instead. How to repeat: mysql> select from_unixtime(100000000000); +-----------------------------+ | from_unixtime(100000000000) | +-----------------------------+ | 2008-07-11 08:56:32 | +-----------------------------+ 1 row in set (0.00 sec) mysql> select unix_timestamp('2008-07-11 08:56:32'); +---------------------------------------+ | unix_timestamp('2008-07-11 08:56:32') | +---------------------------------------+ | 1215752192 | +---------------------------------------+ 1 row in set (0.00 sec)
