Thanks, I installed the attached to simplify a bit further. A nice
consequence of these recent changes is that we get to remove some pragmas.
The first patch is for Gnulib; the other two are for Coreutils.From e14d7e198f96039dbc4fb2118739e6ca1fc4cec6 Mon Sep 17 00:00:00 2001

Yes, as Bruno mentioned, we know of no way to find the boot time on
Alpine. When Emacs cannot determine the boot time, it pretends that the

Now that I've implemented this method in gnulib's 'readutmp' module
and built coreutils with that, I see t

Indeed, this provides the boot time with a resolution of 1 µsec. Whereas the
/proc/uptime approach only ha
