In converting a SVN repository to git, the commit timestamp is
generated incorrectly. I use "git svn fetch --localtime" and the
offset from UTC is always set to +0200 (probably because that is the
current local offset here, i.e. Europe/Berlin) even for times when it
should be +0100.
For example, in my SVN working copy I get
$ svn log -r152
------------------------------------------------------------------------
r152 | urs | 2010-08-16 11:05:52 +0200 (Mon, 16 Aug 2010) | 2 lines
Add error checks on input file streams
------------------------------------------------------------------------
$ svn log -r158
------------------------------------------------------------------------
r158 | urs | 2010-11-24 00:24:13 +0100 (Wed, 24 Nov 2010) | 16 lines
Make code portable to Linux/amd64
After converting to git using
$ mkdir use
$ cd use
$ git svn init -s file://$HOME/SVN/use
Initialized empty Git repository in /home/urs/GIT/use/.git/
$ git svn fetch -q -A ../ADM/git.svn-authors --localtime
r1 = 12cb83315be96e594a98b42db7ae57d19e0c7973 (refs/remotes/origin/trunk)
...
r162 = 99ff393f1d64f330b14d6e06412b94fd3023d616 (refs/remotes/origin/trunk)
Checked out HEAD:
file:///home/urs/SVN/use/trunk r162
I see wrong commit timestamps:
$ git log

In revision 152 the timestamp is correct, but for revision 158 the UTC
offset is +0200 instead of +0100. Then, of course, also the POSIX
timestamp in the commit object is wrong:
$ git cat-file -p c6b4f7aaa66650a16de67d32fb83d541b1973331
tree ff4528220ddcf8beca9f4958fbb947d5ed85808e
parent edcaeb292153663664d850bafe1dad12daab4165
author Urs Thuermann <urs@xxxxxxxxxxxxxxxxx> 1290551053 +0200
committer Urs Thuermann <urs@xxxxxxxxxxxxxxxxx> 1290551053 +0200
Make code portable to Linux/amd64
...
$ date -d@1290551053 +%F\ %T\ %z
2010-11-23 23:24:13 +0100
The correct timestamp would be 2010-11-24 00:24:13 +0100, or, as a
POSIX time_t 1290554653.
I could find the bug grepping through /usr/lib/git-core/git-svn, maybe
it's in GIT::SVN::Fetcher or some other GIT::SVN module.
Is a fix available for this bug?
