I have used a freeware program to track my time for years. "AllNetic Working Time Tracker" is available for free from snapfiles.com and other download sites. A 25 dollar upgrade allows you to print out reports. Works great for other tasks in addition to working on ArchiCAD. Whenever you start to use your computer a small window will pop up and remind you to start tracking your time. Set up jobs and tasks and start counting. Check it out.
