Tor log dates imprecise

Hi Nick. Tor's log file uses the local timezone and lacks the year in its log file entries...

Apr 06 11:03:39.000 [notice] Tor 0.2.7.0-alpha-dev (git-4247ce99e5d9b7b2) opening new log file.
Apr 06 11:03:39.832 [notice] Tor v0.2.7.0-alpha-dev (git-4247ce99e5d9b7b2) running on Linux with Libevent 2.0.16-stable, OpenSSL 1.0.1 and Zlib 1.2.3.4.

This is fine, but has meant some hacks for arm which reads the log file to prepopulate that information. For instance, arm pretends the year is always 2012 to ensure log files made on leap years are readable (otherwise February 29th isn't a thing, see legacy/trac#5265 (closed)).

Feel free to close this as 'no plan to fix' if you'd like. Just thought I'd run this by you to see if iso8601 timestamps or something more complete would be preferable.
