check-zone-expiration(1) displays how long until a zone's records expire


# check-zone-expiration will expire in 26 days, 2 hours, 16 minutes, 36 seconds will expire in 12 days, 17 hours, 7 minutes, 1 second

# check-zone-expiration -m 1123200 will expire in 12 days, 17 hours, 6 minutes, 22 seconds


The check-zone-exiration script reports how long until a zone will expire by querying for the zone's (top level) RRSIG and calculating how much time is left before the signatures will no longer be valid. It will then report how much time is left in human readable form.

If the -m switch is provided with a time argument (in seconds), it will only print output for zones that have less than that time left.


Minimum reporting time, or else be silent for the zone
