# The Time Tab
This lesson explains the layout of the **Time** tab in a case.
### Time tab
The Time tab allows you to make time entries against a case. Time entries are used to track the time spent on the case. For example, each working day can be recorded to calculate the average working day when deciding upon a fixed fee.
You can also use time entries in the invoicing functionality. Entries with a billing rate against them will be calculated into any invoice generated against the case.
To add a new time entry, click **Add Time Entry**.
### Adding a time entry
{% stepper %}
{% step %}
### Enter the time entry details
After choosing to add a new entry, fill out the details.
The date is automatically filled with the current date, but can be changed by clicking the field. Enter a duration and a description of the time entry.
{% endstep %}
{% step %}
### Enter billing details
If you are billing the client for this time, fill in the right-hand column.
The **Description** field allows you to select a billing rate, while the **Tax** field lets you choose the relevant tax option. The **Rate** field is automatically populated when you select a billing rate, but can be edited for one-off billings.
{% endstep %}
{% step %}
### Select the system user and save
Select the system user who made the time entry.
Once you have completed these details, click **Save Time** to create the entry.
{% endstep %}
{% endstepper %}
You can also add time entries using the timer function, which is explained in [this](/user-documentation/time-recorder.md) lesson.
### Time entry saved
Your new time entry will now appear against the case. It can be edited or set inactive using the corresponding dropdown menu.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.agilecase.com/user-documentation/the-case-tab/the-time-tab.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
