[Quilt-dev] Submit patch: use UTC in patch timestamps

[Joe Green]

The "patch" and "date" documentation recommend using the environment 
variables "LC_ALL=C TZ=UTC0" to create standardized date information.  I 
think this would be a good thing for quilt to do; the attached patch 
implements this for the timestamps quilt creates for generated diffs.
