--- Comment #1 from Jamie Landeg-Jones <jamie at catflap.org> ---
The man page for newsyslog.conf(5) says that if both a size and a time interval
are specified, BOTH conditions must be satisfied for the file rotation to take
place:

 > Time based trimming happens only if newsyslog(8) is run within one hour of
the specified time.  If an interval is specified, the log file will be trimmed
if that many hours have passed since the last rotation.  When both a time and
an interval are specified then both conditions must be satisfied for the
rotation to take place.

This is wrong. The rotation will take place if EITHER condition takes place.

Consider this test, creating an entry that will be rotated when the file size
reaches 10Mb, and the file is older than a day:

Cheers, Jamie
