As I understand it, the leapseconds file (like most of the other files in the
glibc timezone directory) is intended only for test data, and is not kept
up-to-date. Perhaps this should be stated more clearly in the files' headers.
Another possibility would be to remove these files, as purposely out-of-date
files cause confusion among glibc contributors.

Ah, I was under the impression they were used when converting in and
out of "right" timezones. But now I see that information is in the
tzinfo file itself.
My bad.

Maybe move them to e.g. timezone/test-sources? (We already have
timezone/testdata for *binary* timezone files used as test inputs to the
timezone code, so it's probably a good idea to keep the different kinds of
test inputs separate.)

Yeah, well, it's also getting shipped as part of the binary
distribution, at least on ubuntu, so if it's just test data then that's
weird...

Distributions should be building from the separate tzdata package, not
from glibc sources, which haven't installed the binary timezone data for
several years.
