Editing Timestamps on Trackpoints in Viking

I use Viking GPS data editor and analyzer  for tracking bike rides and routes. My GPS and phone keep dying and I wanted to fix some tracks.  So I looked at the source and changed it to allow editing the time on points. It's a simple two-line change there is a diff file here: http://farcry.ca/blog/files/viking-edit-point-time.diff It is against commit b22233bdbe84cee4af1cd2433cd25d63a300088c
