In the menu bar in the achievements tab I can access the current UTC time, which is good, since I am not living in that time zone.
In chat this bar is missing. Instead messages are marked with my local time zone. In the transcript, however, the time stamps are again UTC, but there is no way to tell which time it is at the moment - which is sometimes a little confusing when you are reading the transcript of the same day.
I would appreciate having a clock on these pages.
