But this resolves the 32-bit issue only, correct?

I did end up compiling the latest version (27.0.50, as reported by 'emacs --version') cloned from

git://git.savannah.gnu.org/emacs.git

on a 64-bit system and

(format-time-string "%a %b %d %H:%M:%S %Y GMT" 67768036191676800 t)

still chokes with the "Specified time is not representable" error. As before, the same expression evaluates fine to

"Wed Dec 31 23:59:59 2147485547 GMT"

with the smaller number

67768036191676799 = 67768036191676800 - 1

If it helps, I see no problem on the latest pull of emacs-27. I'm on
Linux 3.16.0-10-686-pae #1 SMP Debian 3.16.74-1 (2019-09-24) i686
GNU/Linux. Screen-shot below.

Yeah, if you have the latest pull, then you have my fix for this
problem.

Sorry to butt in.

Butting in is what the bug tracker is for.  :-)
