From e451d06bf39df35d1106ad9bde5e38505533d805 Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Mon, 12 Apr 2010 16:25:28 -0700 Subject: [PATCH] tag.c: Parse tagger date (if present) Just like with committer dates, we parse the tagger date into the struct tag so its available for further downstream processing. However since the tagger header was not introduced until Git 0.99.1 we must consider it optional. For tags missing this header we use the default date of 0. Signed-off-by: Shawn O.
