git repo port issues?

https://cgit.freebsd.org/ports/

The latest update to "main" is :

author    Yuri Victorovich <yuri@FreeBSD.org>  2023-01-03 14:49:38 +0000
committer Yuri Victorovich <yuri@FreeBSD.org>  2023-01-03 14:49:38 +0000

I.e. A year old. Reading the commit message, it does appear to be a wrong
clock, rather than an old message, but whilst the author date is local to
the author, I thought the commit date was centralised.

If nothing else, this does seem to bugger up "commits since <date>"
within git itself.

Cheers, Jamie
