[PATCH] apply: Recognize epoch timestamps with : in the timezone

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Some patches have a timezone formatted like â-08:00â instead of
â-0800â (e.g. http://lwn.net/Articles/131729/), so git apply would
fail to recognize the epoch timestamp of deleted files and would
create empty files instead.  Teach it to support both formats, and add
a test case.
