I have been meaning to fix this up for a long time, but so far real work keeps getting in the way. The idea is that C-C t brings you to this week's time tracker buffer, and then you use (C-c C-x C-i/C-c C-x C-o) to start and stop timers.

The only even slightly clever is stopping the timer and saving on quitting emacs, which I borrowed from the someone on the net.

• Updated dependence on mhc removed.
• Updated 2009/01/05 Fixed week-of-year calculation

The main guts of the hack are here.

The result might look like the this (works better in emacs org-mode. C-c C-x C-d for a summary)
