Show JS property "lastStateUpdateTimestamp" in custom Widgets

I’m using OH Version: 5.0.1

Since an update to JS scripting (v5.11.1), there are additional item properties such as lastStateUpdateTimestamp or lastStateChangeTimestamp.
Until now, I had created several items for this, but with the new properties, they would become obsolete.

Can these properties also be used in custom widgets?

My attempts with a test widget were unsuccessful.

uid: test_widget
tags: 
props:
  parameters:
    - context: item
      description: An item to control
      label: Item
      name: item
      required: false
      type: TEXT
  parameterGroups:
timestamp: Oct 12, 2025, 1:47:21 PM
component: f7-card
config:
  title: ‘=(props.item) ? "State of " + props.item : “Set props to test!”’
  footer: ‘=dayJS(items[props.item].stateLastUpdateTimestamp)
    .format(“DD.MM.YYYY HH:mm:ss”)’
  content: =items[props.item].displayState || items[props.item].state

No. JSScripting and the javascript-like widget expressions are two separate systems. Your items are not obsolete. They remain the best way to access this information in widget expressions.

Thank you, I had already suspected it, it’s a pity that in some places it would be a lot easier
