Time categories are typically the means of tracking time for individuals. Jarrison Time will have existing time categories in place. Any additional time categories needed can be created from the Time Categories configuration window reached from Setup on the menu bar.

From Time Categories screen time categories can be added, removed, or renamed as needed. JT has no limit to the number of time categories stored.
It is also possible to apply the Set default as ‘Allow auto break deduction’ for allocations for each time category. If this option is ticked then each time the time category is added in the Allocations tab of Day Programs, the Allow Auto Breaks to deduct from this time category option will be selected (it can always be de-selected later).

You can include any Time Category in the Annual Overview, by selecting the Use in Overview option.
If the Job Costing module is in use a ratio can also be applied for costing e.g. OT1.5 would have a ratio of 1.5.
