Whenever a time entry is created, the user will be asked to enter the top-level time category.

It is this choice that determines the different time codes that need to be entered.

Time Categories are defined within Admin > Time and are defined by:

• A Name and unique System Name.
• A flag to indicate whether they are billable or not.
• And the default time classification (or set of fields) that are shown - see Time Recording: Configuring Time Classifications‍.

In addition to the default time classification, you can also specify a number of Rule Groups to vary the time classification that is used.

Within a rule group, you can specify that a given time classification is shown based on:

• Matching rules that are evaluated for a time container (the time container is typically the matter but could also be the SoW).
• Matching rules that are evaluated for the work item (typically a task) where time is being recorded against it.

Using matching rules, you can:

• Vary the time capture by different matter types - for example, using the JCode classification for dispute matters and a separate classification for real estate matters.
• Vary the time capture for different clients - for example, your client may wish for you to add additional time codes for their matters.
