title: Git-Svn: Retain commit timestamp after dcommit
body: <p>I've been using Git &amp; Git-Svn for a year or so now and somehow just noticed that, after a <code>dcommit</code>, my commit history is preserved, but the timestamps aren't. In other words, each git commit entry is retained, but in Svn each commit has the same timestamp (more or less).</p>
  
  <p>It's not unusual for me to work remotely for a day or so at a time, making any number of commits throughout that time. Ideally, I'd like for my svn log to reflect the times I made those commits to git rather than the time that the commit (along with any other commits) was <code>dcommitted</code> to svn. Is that possible?</p>
  
  <p>Thanks.</p>
