From: Jiaying Song <jiaying.song...@windriver.com>
This patch replaces "%010ld" with "%019" PRIdMAX and casts time() to
intmax_t, to prevent formatting overflow on systems where long is 32-bit
but time_t is 64-bit.
The previous formatting could truncate high-bit time values, causing
unexpected behavior in mail queue operations on systems with time beyond
2038.
This ensures safe formatting of time values across 32-bit and 64-bit
systems.
