Subject: [PATCH] Fix 2038 year problem in timestamp handling
The minicoredumper uses 'long' type for timestamp which causes
overflow on 32-bit systems after 2038-01-19. This leads to
incorrect timestamp formatting in core dump directory names.
Change timestamp variable from 'long' to 'time_t' and use
'strtoll' instead of 'strtol' to handle 64-bit timestamps
properly on 32-bit systems.
