Time Log Software

I'm about to start a project that will be charged at an hourly rate. Does anybody have recommendations for free time logging software that will track the time spent on a project?

I don't know of any free software for that purpose. Just use a spreadsheet, they can also calculate with time and not just money. ;-)

If you got a webhotel with php and mysql: WR Time Tracker

Or I think you can just make an accont:

I use Excel, flexible, loads quickly, easy etc. Used it to track the 900+ hours of my last game.

edit: nm... not free.

I use Google Spreadsheets for my time lists (though any spreadsheet will do).
Its easy making it calculate everything for you.

You can also find a free Excel alternative as part of OpenOffice

Code it yourself?
