Time Variable Icon

The presence of a time variable in the network is highlighted by the hourglass icon in the Status Bar. Clicking the icon prompts you to remove the time variable from the network. Doing so, however, could lead to Formulas no longer being valid because the corresponding probability distributions are no longer defined; in this case, the affected nodes are marked with a warning triangle. The icon can only be clicked in Modeling Mode. In Validation Mode, it is inactive and grayed out.
