 Torbutton could make use of a getinfo command to reduce the fingerprinting
 issues that a user has wrt their Date() object (see #2940).

 However, the threading support in Firefox is not good enough for us to
 easily make a full tor controller that listens for events. It would be
 much easier if the current skew (ideally down to milliseconds if possible)
 was available as a getinfo command, so that Torbutton could just query it
 and update the browser's time offset.

 I am making this a 'major' enhancement because clock skew is an important
 issue to address to reduce fingerprinting.
