No, not yet. :) The format of the timestamp doesn't really matter here. 
It's just added to the footer of some of the manpage output formats 
(pdf, html). I'll investigate if there's a more portable way to add it.

Hm, that's strange. I don't know where the "d" command comes from. There 
are only "s" commands in the sed statements...
I'm also wondering why "make" tries to rebuild dvisvgm-man.xml at all. 
dvisvgm.1 should be present in the source tarball so that there's no 
need to rebuild it.

Unfortunately, I don't own a Mac and have no deeper knowledge of macOS. 
Thus, I can't really help you with this one.
