From a1980c4efcfea516e2ba442bf7e56a39d9a7933f Mon Sep 17 00:00:00 2001 From: Anders Kaseorg Date: Wed, 29 Sep 2010 16:49:49 -0400 Subject: [PATCH 1/2] apply: Recognize epoch timestamps with : in the timezone MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some patches have a timezone formatted like ‘-08:00’ instead of ‘-0800’ (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.

Take this into account when searching for the start of the timezone (which is the end of the filename). This does not actually affect the outcome of patching unless (1) a file being patched has a non-' ' whitespace character (e.g., tab) in its filename, or (2) the patch is whitespace-damaged, so the tab between filename and timestamp has been replaced with spaces.
