Timers allow you to accurately track time spent on Work Items. You 'Start' the timer when you start working on the Work Item and 'Stop' it when you are done. You can also 'Pause' the timer if you temporarily stop working on a Work Item and 'Resume' it when you work on it again. For example, assume you have two Work Item; Task T1 and a Workflow W1. When starting on T1 you start its timer. After a couple hours you need to switch to W1. You can either click 'Pause' for the timer for T1 and then 'Start' the timer for W1 or you can directly click 'Start' the timer for W1 which will automatically pause the timer for T1. When you need to switch back to working on T1, click 'Resume' for the timer for T1.

You can have only one 'active' (ticking) timer at a time and is indicated in Red.

To use timer to record time:

From the actions menu ☰ of the work item (App item or Task), click on Timer.
The new timer on the selected task is started. You can see the timer on the top-right of your menu bar.
Click on the timer to see the different options for this.
To add time, click on fill time icon. This will open an Update Progress & Time window with the time pre-filled. You can modify the hours if required. After you fill time the timer for that Work Item is reset. To remove the Work Item from the list click on 'Delete' icon.

Adding a timer on a new work item will start the new timer. Any existing one will be paused.
If you add the timer again on the existing work item again, then no action will be taken i.e. the timer will continue counting.

If the 'Timer' option is not available on a particular work item, then check the following:

The 'Allow Time' option on the work item is unchecked.
The project under which the work item is present is in 'In Planning' or 'Archived' phase and your company does not allow time on these phases.
The 'Time Sheet' module of your company is disabled.
