A classification is a segment (set of fields) that captures additional information about a time entry. For example, a classification called Activity might require the user to select a code from an activity code set. Classifications can be mandatory or optional, and can apply at the point of entry or submission.
Classifications are applied globally. If you need different classifications for different work types or matter types, use Category Rule Sets.

Using the screenshot above as an example, a time classification has been defined containing the Time Code Sets of Phase and Task and Activity.
Time Code Classifications are maintained under Admin > Time and consist of one or more segments.

For a given segment, you can specify the following.
| Name | The name of the segment as it will appear for your time entry users |
| Enabled | Controls whether the field displays on the capture screen. Disable a field to remove it without deleting it. |
| Mandatory for entry | Whether your users must enter this code before saving their time entry or not. |
| Mandatory for submission | Whether your users must enter this code before submitting their time entry or not. |
| Capture Type | Whether the user should enter a Time Code Set or a memo field. |
| Time Code Set | If the time capture type is "Time Code Set", select the Time Code Set. |
| Default Time Code for Stopwatches | When a stopwatch is stopped, you can specify the default time code that is recorded. |
You can only delete time classification segments that haven't been used. Once they have been used, you can only disable them.
