After fooling around with --format=ustar and --format=pax a bit more 
with tzdb, and discovering the Y2242 problem that I'd forgotten about in 
ustar format, I installed the attached further patch. It changes the 
documentation to suggest 'delete=atime,delete=ctime' instead (more 
robust to shell expansion). And it downgrades its suggestion of 
delete=mtime because that stops working after 2242. (No time like the 
present...)

The other two patches bring the doc a bit more up to speed on boilerplate.

If you're curious, the companion patch I installed into tzdb is here:

https://github.com/eggert/tz/commit/7a200f2b3ef4ea71d5091d8f712bc40d8c340381

It uses "--format=pax --pax-option='delete=atime,delete=ctime'" instead 
of "--format=ustar". Since the tarball contains only files with integer 
timestamps, the two options are equivalent until the year 2242, when the 
latter will stop working and the former starts using pax extensions.
