timelog is a silly little app to help with time logging.

It reads the dhcp lease renews and releases to give an approximation of when you started and finished working.

Here's an example from my machine:

$ timelog

Mar 30 18:57:35 localhost dhcpcd[2122]: wlan0: offered 172.31.1.110 from 172.31.1.1

Right now it is very unportable.

Patches to make it more portable are very welcome.
