postlogd may receive events that were sent earlier (by smtpd, qmgr,
etc.) and that were still queued up in the kernel.
The time stamp prefix string in a logfile record is formatted in
the sending process, at the time that that process gets from the
kernel using the time() system call. If the clock inside a process
does not advance, then MacOS is doing something unusual.
