Time tracker redux

[DANIEL MENDOZA]

Okay, from the limited response to my earlier inquiry as to whether others are using CA Time Tracker . It appears to be underdeveloped or purposely avoided. My new question is what method do you use to keep track if you're billing by the hour? My supervisor is intent on me keeping track of redesigns which adversely effect the margin jobs are sold at. Any input ,any easy and accurate ways to keep the total draw time recorded?
Thanks ahead for any help.
