Copr spec file parser does not like '%S'

[joe94]

Debugging why copr builds are failing:

Writing config into /tmp/copr-rpmbuild-algqo_4b/obtain-sources/.config/rpkg.conf
Running: rpkg srpm --outdir /tmp/copr-rpmbuild-algqo_4b --spec /tmp/copr-rpmbuild-algqo_4b/obtain-sources/tr1d1um/deploy/packaging/tr1d1um.spec

cmd: ['rpkg', 'srpm', '--outdir', '/tmp/copr-rpmbuild-algqo_4b', '--spec', '/tmp/copr-rpmbuild-algqo_4b/obtain-sources/tr1d1um/deploy/packaging/tr1d1um.spec']
cwd: /tmp/copr-rpmbuild-algqo_4b/obtain-sources/tr1d1um
rc: 0
stdout: Wrote: /tmp/copr-rpmbuild-algqo_4b/tr1d1um.spec
stderr: error: /tmp/copr-rpmbuild-algqo_4b/tr1d1um.spec: line 29: %S: argument expected
can't parse specfile

Output: ['tr1d1um.spec']

I verified the version of the date command matches the one we expect.

date --version

So this tells me that their .spec file parser changed somehow.

@kcajmagic, what do you think about switching to this format:

date -u '+%c'
Tue 10 Nov 2020 12:07:37 AM UTC

It works fine on copr and it contains all the info we want.
