I see.

I don’t think this is the issue. I’m using apfs, which a quick google
tells me has ‘nanosecond’ accuracy. Besides:
-rwxr-xr-x 1 alan staff 7057932 21 Jan 19:37 bootstrap-emacs
-rwxr-xr-x 1 alan staff 7057932 21 Jan 20:49 temacs

This indeed looks like it’s probably the issue. I think I’ve had that
message for as long as I’ve been building Emacs. I just assumed it was
informational and not an actual error.
If I comment out this:
$(srcdir)/macuvs.h $(lispsource)/international/charprop.el: \
bootstrap-emacs$(EXEEXT) $(bootstrap_pdmp) FORCE
$(MAKE) -C ../admin/unidata all EMACS="../$(bootstrap_exe)"
the errors go away.
