This reverts d4ff6f30da as
that commit was incorrect. We actually had a timezone
translation occuring in gwtjsonrpc that we didn't want,
so the Timestamp objects were already in the user's own
timezone, which is why we had to use the reverse version
of the offset to get them to display right.
Now that gwtjsonrpc is fixed, we shouldn't be doing this
at display time.
