Also, the "date +s" and the "date -u -r" don't do what you think they do...

I think that `date +s' is a typo - probably missing a `%' as you've
noticed - while `date -u -r' (that's after the `||') should work on
most BSD systems.

I'm assuming that the BSD 'date' takes -r as a timestamp rather than a
filename. Somebody
on a BSD system will need to check that.
This is what happens on NetBSD (if I'm not missing something the
it is similar to what happens with GNU date):
| % cat /tmp/date.sh
| DATE_FMT="%Y-%m-%d %T +0000"
| SOURCE_DATE_EPOCH="${SOURCE_DATE_EPOCH:-$(date +%s)}"
| date=$(TZ=GMT0 date --date="@$SOURCE_DATE_EPOCH" "+$DATE_FMT" 2>/dev/null ||
date -u -r "$SOURCE_DATE_EPOCH" "+$DATE_FMT" 2>/dev/null || date -u
"+$DATE_FMT")
| echo $date
| % date && sh -x date.sh
| Mon Jul 23 23:57:26 CEST 2018
| + DATE_FMT='%Y-%m-%d %T +0000'
| + date '+%s'
| + SOURCE_DATE_EPOCH=1532383046
| + TZ=GMT0 date '--date=@1532383046' '+%Y-%m-%d %T +0000' 2>/dev/null
| + date -u -r 1532383046 '+%Y-%m-%d %T +0000' 2>/dev/null
| + date='2018-07-23 21:57:26 +0000'
| + echo 2018-07-23 '21:57:26' +0000
| 2018-07-23 21:57:26 +0000
