Preserving timestamps

Well, but mercurial won't manage the timestamps of (hg root)/.timestamps/*
either, so all your timstamps would still be lost

... unless you use tar (or some other timestamp aware packer) to pack the whole directory before commit. This should be doable, but I see no real advantage over my approach, except that you don't depend on python (which we all do anyway). 

OK, the .timestamps/* structure might also be more accessable than the pickle-file. But then i would prefer a human-readable 
.timestamp file, just containing the human readable timestamps, which you can apply using touch -d.

Have a nice day,
