- Times: Relative - Allows you to select a group of up to the last 100 times.
- Times: Absolute - Allows you to select one or more absolute times. When choosing absolute times for the first time, McIDAS-V needs to query the ADDE server for the times. This may take some time. To select more than one time use Ctrl+click or Shift+click. See the Timeline Controls section for details on its use. Click on the
Select Day button to narrow down a large dataset to one day.
- Match Time Driver - Selects times that match the time driver, assuming one has been set. For more on this feature, see Time Matching. This option is only available if a time driver has been set in the session.
