Subject: dgit clone: Set timestamps in cloned tree to a single unified time.
X-Git-Tag: archive/debian/2.9~31
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=dgit.git;a=commitdiff_plain;h=4c09c958f20263601483e0150caf4787a064aa5e

dgit clone: Set timestamps in cloned tree to a single unified time.

This makes it less likely that the user will trip over any
timestamp-dependent FTBFS bugs (eg #842452).
