Description olaf 2020-01-22 09:14:24 UTC 
date '+%s' shows wrong value.

Linux: 1579684042
FreeBSD: 135

According to 'man strftime', %s should be 'number of seconds since the Epoch, UTC'

# date '+%s'
513

# date -r 513

Which date binary is that? What is the date output without modifiers?

$ uname -psr
FreeBSD 12.1-RELEASE-p1 amd64
$ which date
/bin/date
$ date '+%s'
1579687351
Comment 2 Pawel Biernacki freebsd_committer freebsd_triage 2020-01-22 10:11:12 UTC 
Can you please share the output of:

sysctl kern.boottime
date; date -r `date '+%s'`

Can't confirm on various installations of 13-C.

I investigated further, and it turned out that a tool from sysutils/munin-contrib was setting the (wrong) date to 1.1.1970 instead of doing a convertion task.
