Elapsed Time

A retentive timer is used to keep track of how much time something has been in a particular state.

This can be used to time how long something has been in an alarm state for example or how long it

has been since a proﬁle or step ran. The output can be used to trigger an event if the elapsed time

has grown excessive.
