Hi,
Using date from coreutils 8.31-1 on Arch Linux.
This surprised me.
$ TZ=UTC0 /bin/date -d '1pm + 2 hours'
Wed 8 May 15:00:00 UTC 2019
$ TZ=UTC0 /bin/date -d '13:00 + 2 hours'
Wed 8 May 12:00:00 UTC 2019
The documentation doesn't suggest `1pm' and `13:00' are treated
differently. `--debug' helps.
$ TZ=UTC0 /bin/date --debug -d '1pm + 2 hours'
date: parsed time part: 01:00:00pm
date: parsed relative part: +2 hour(s)
...
$ TZ=UTC0 /bin/date --debug -d '13:00 + 2 hours'
date: parsed time part: 13:00:00 UTC+02
date: parsed relative part: +1 hour(s)
date: input timezone: parsed date/time string (+02)
...
It looks like parsing is broken in the second case.
The result I wanted can also be obtained my omitting the `+'.
$ TZ=UTC0 /bin/date -d '1pm 2 hours'
Wed 8 May 15:00:00 UTC 2019
$ TZ=UTC0 /bin/date -d '13:00 2 hours'
Wed 8 May 15:00:00 UTC 2019

Cheers, Ralph.
