It is (that comes from RPM itself), however the directory is empty.
That feels like a bug in OBS then. IIUC this macro can be specified on the rpmbuild's cmd line. Can't it set the %_specdir to be the same as %_sourcedir?
Nothing about RPM mandates that %_specdir is actually *used* for anything.
But this is not the case, is it? %_specdir is defined and points to an actual directory. Having said that, I am not against the change, but maybe we can document this weirdness somewhere? Also, with the latest specfile discussion I'll let Andrea take a look.
RPM internally populates a specfile variable that is the true pointer to the spec file, regardless of path. This is not exposed as a macro despite attempts to do so[1]. There is no rule that the spec file *must* come from %_specdir, and it's really only used for the location to store the specfile when extracting an SRPM.

I'm inclined to just delete all the source epoch stuff from the spec and rely on the build environment set it if they want reproducable builds.
Considering that RHEL 8 doesn't have the change to turn on SOURCE_DATE_EPOCH[2], I am inclined to keep it.
We can just wrap the current setting in "%if 0%{?rhel}" then, so we honour the setting from Fedora.
