Within Teamwork.com, you can start a timer or add a time log manually in the Time area of a project.
Note: The ability to log time on a project is dependent on your project permissions. A project admin or site admin can grant these permissions to standard users or client users on an individual basis.
In the top right of the Time tab of a project, you can either log time or start a new timer.

Logging time
By clicking the Log Time button, you can manually log time directly to the project.

Choose the details for the time log:
- Who logged the time (the default will be the person logged in)
- Date
- Start time
- End time
- Time spent
- Billable or non-billable (your choice will be remembered next time you log time)
- Description
- Associate the time entry with an existing task
- Add a tag to the time log
Starting a timer
Selecting Start Timer will start a timer in the lower left-hand corner of the browser window.
Once the timer starts running, it will run until you choose to stop the timer by either pausing or selecting the Log option.
You can also expand the timer by selecting the up arrow; from here, you can either delete the timer or select to mark the time as billable or non-billable.

Once you click Log, you will be prompted to confirm that you want to stop the timer and log the time.
You can then edit the time log (choose whether the time is billable or non-billable, associate the the time with an existing task, or add a description). Once you save those details, the time will be logged against the specified project (and task, if you chose one).
