From: Uwe Kleine-König <u.kleine-koenig@baylibre.com>
This is easier to handle because you can just consult date(1) to convert
between a seconds-since-1970 value and a date string:
$ date --utc -d @3661
Thu Jan 1 01:01:01 AM UTC 1970
$ date -d "Jan 1 12:00:00 AM UTC 1900" +%s
-2208988800
The intended side effect is that this prepares the test for dates before
1970. The division of a negative value by 86400 doesn't result in the
desired days-since-1970 value as e.g. secs=-82739 should map to days=-1.
