Subject: [PATCH] lib/timeutils: Add %s (seconds since the Epoch) to parse_timestamp()
Date: Tue,  6 Sep 2022 10:04:36 +0300	[thread overview]
Message-ID: <20220906070436.684-1-peter.ujfalusi@linux.intel.com> (raw)

The %s comes handy with for example dmesg with the --since within scripts
to handle log rages.
