Example of a Time Settings dialog

Transient dataset time values are displayed in the Time Steps window using either a relative time format (e.g., 100.0) or an absolute date/time format (e.g., 1/12/2006 3:23:48).

Changing Time Settings

To change the time settings, select the Menu command Edit | Time Settings or right-click on the Time Steps window and select Time Settings to open the Time Setting dialog.

Time Settings Dialog

The following options are available in this dialog.

  • Zero Time
