0-hour an error in ymd_h but not in ymd_hm

[drikkes-jue]

Why is
ymd_h("2021-10-26 0")
an error ?

ymd_hm("2021-10-26 0 0") works fine!

[vspinu]

Works fine here:

> ymd_h("2021-10-26 0")

What error, what version, what OS?

[drikkes-jue]

Sorry for the sloppy bug report.

Here the version info

$ uname -a
Linux hibiscus 5.3.18-lp152.95-default #1 SMP Tue Oct 5 07:30:50 UTC 2021 (7cfc6af) x86_64 x86_64 x86_64 GNU/Linux

Distribution: openSUSE Leap 15.2

lubridate: both Version: 1.8.0 from CTAN and 1.7.8 from openSUSE (package
R-lubridate-1.7.8-lp152.1.10.x86_64) show the bug

While preparing this clarification I detected that this bug is language
specific, it works in English but not in German.
See for yourself:

Interesting. This part should not be language dependent. Investigating.

[vspinu]

I cannot reproduce by just setting the LANG. What is the entire output of locale for you?

[drikkes-jue]

On my account -- where I did the tests described earlier -- I get

$ locale
LANG=de_DE.UTF-8
LC_CTYPE="de_DE.UTF-8"
LC_NUMERIC=C
LC_TIME="de_DE.UTF-8"
LC_COLLATE=C
LC_MONETARY="de_DE.UTF-8"
LC_MESSAGES="de_DE.UTF-8"
LC_PAPER="de_DE.UTF-8"
LC_NAME="de_DE.UTF-8"
LC_ADDRESS="de_DE.UTF-8"
LC_TELEPHONE="de_DE.UTF-8"
LC_MEASUREMENT="de_DE.UTF-8"
LC_IDENTIFICATION="de_DE.UTF-8"
LC_ALL=

but I also tested on a newly created account on debian 11, got the same result
and there locale gives:

$ locale
LANG=de_DE.UTF-8
LANGUAGE=
LC_CTYPE="de_DE.UTF-8"
LC_NUMERIC="de_DE.UTF-8"
LC_TIME="de_DE.UTF-8"
LC_COLLATE="de_DE.UTF-8"
LC_MONETARY="de_DE.UTF-8"

Thanks for reporting this. Finally got down to fixing this.
