timer ?

[betty]

Anyone out there know of a timer that I can use with Ubuntu 10.04. I am 
doing online work for people and right now am writing down the start and 
stop times then converting them into hrs and min for my billing. I know 
my palm has one, but then i'd have to be messing with that too. (no i am 
not a lawyer).
thanks !!
