The date plugin seems to have several problems when compiled with musl.

I had a look around but cannot pinpoint the problems.

It also is relying on features.h which is discouraged.

Thank you for reporting this problem!

@tom-wa Do you have an idea which parts are not portable? The README says POSIX.1-2001 should suffice?

[markus2330]

The messages of the unit tests are useless. The tests should at least print the error+warnings of the plugin.

Just checked again, posix strptime doesn't support %z/%Z for timezones needed by rfc822. best course of action would probably be ignoring the timezone in strptime and implement a check for it, but i'm not sure if i can do it this week

Under CentOS 7 the same problem occurs:
