While I did mention filesystem timestamps on IRC as an example, and they
are relevant for say make, do they matter here?

Or rather, if Clojure's only looking at the timestamps in the jar file,
then those may have a known (fixed) resolution, and so we'd just need to
make sure that the .clj files are at least that much older than the
corresponding .class files inside the jar.

Though I'd probably still pick 1s or more just so that an unpacked jar
will still have the right timestamp ordering on the vast majority of
filesystems.

Or perhaps we're not (re)building the jar(zip) manually, but building a
new one after round-tripping the files through the current filesystem?

...in which case perhaps an offset of a second or more is still
sufficient.
