Unreasonable values for 'expire' (after 9999-12-31
on Linux, before 1975-01-01 on *BSD) get divided
by 86400 (number of seconds in a day) when too big
or multiplied by 86400 when too small.
Tested on CentOS 6 (Salt 2015.5.5) and FreeBSD 10.2
(Salt 2015.8.0) with following values:
- 24854 (2038-01-18 in days since epoch)
- 157766400 (1975-01-01 00:00:00 UTC in seconds since epoch)
- 3313526400 (2075-01-01 00:00:00 UTC in seconds since epoch)
- 16000 (2013-10-22 in days since epoch)
- 18000 (2019-04-14 in days since epoch)
