+Channels with localised time
+-----
+LogBot now also supports having localised time on a per channel basis using the pytz library, allowing you to have the logs of specific channels use different timezones.
+Installing pytz should be as simple as running `easy_install --upgrade pytz`, see http://pytz.sourceforge.net/#installation for details.
+Don't worry, if you don't have pytz installed, LogBot will continue to show the logs timestamped with your system's localtime as it used to.
+
+Next you can create a simple text file at `~/.logbot-channel_locations.conf` (or wherever `CHANNEL_LOCATIONS_FILE` in logbot.py points to).
+On each line you can now specify a channel name, and the timezone location of which it should use the timezone offset, separated by a space. Example:
+
+	#excid3 America/Chicago
+	#netherlands Europe/Amsterdam
+	#aloha US/Hawaii
+	#space UTC
+
+Any channel not specified in this file will use the default timezone as specified in DEFAULT_TIMEZONE, which defaults to 'UTC'.
+
+If you want to see a list of all possible timezone location names you can use, run:
+
+    python -c 'import pytz;print pytz.all_timezones'
