The time extent of temporal data is defined as the duration in time within which the data was collected. Basically, the time extent can be calculated using the minimum and maximum time stamp of the time values in the temporal dataset.
The time extent of the data is used by the time slider to define the time extent within which data will be displayed in the current map, globe, or scene. Calculating the time extent on the layer can also be used to find any errors in the time values of your data.
- Double-click the temporal dataset in the table of contents to open the Layer Properties dialog box.
- Click the Time tab.
- Click the Calculate button.
The time extent of your data is calculated and displayed.
