Summary

Outputs a new Date/Time value only when it changes from the previously stored value.

Description

The **Date/Time Change Only** component monitors the incoming **In** Date/Time signal and compares it to the last output value. If the value is different, the new Date/Time is passed to **Out**. If it is the same, no update is sent, reducing unnecessary downstream updates.

This is useful for: - **Data logging** – recording timestamps only when they change. - **Event tracking** – triggering actions only on new time events. - **Automation** – avoiding redundant processing when time remains unchanged.
