Hi Tim,

This is actually the intended behavior of git-svn.

SVN itself only stores times in UTC and nothing else.  The SVN
repository itself has no timezone information (unless the server it was
on is misconfigured :)

The regular svn client converts the UTC time to the local time (or
based on the TZ= environment).  Using "git svn log" should mimic the
timezone behavior of the regular svn client.

git-svn will only import times as UTC because that's what SVN
gives it.

As a side effect, this also makes it easier for multiple users to
independently create repositories that result in the same commit SHA1s
(and one of the reasons for using dcommit over git svn set-tree).
