Comment (by mikeperry):

 Thank you neel! I really appreciate this. This was originally going to
 fall to me or catalyst. More time for vanguards now :)

 This looks good, but as a note, Tor Browser is going to have to remember
 not to overwrite the TZ environment variable before or while it launches
 Tor for current-time/local to not also be UTC. (This may mean saving the
 previous TZ value before we set it to UTC, and using that in the environ
 for tor).
