I think so.  But maybe not all systems have the right/ zones, and
systems certainly don't agree on how the initial time zone is
configured at boot time.

But DJB didn't invent leapsecs.dat; he got it from somewhere else.
Ah: I found a "leapseconds" file in the tzdata tarball from
<URL:ftp://elsie.nci.nih.gov/pub/>.  That's probably it.  But how do
we compile it into leapsecs.dat?

Actually, I'm not sure we even need leapsecs.dat if we're using right/
zones.  right/ zones are the ones with leap second information
compiled into them.
# echo $TZ; date; mv leapsecs.dat{,-}; date; mv leapsecs.dat{-,}
