Unless I'm doing something wrong I would like to request an improvement to the show_last_changed glance card option.

I have a dashboard on my desk that shows the state of a few entities and I would like to see how long they've been in that state. I've noticed the glance card show_last_changed value will become stale and not update with the current relative-time. However, the logbook card will have an accurate relative time, even without refreshing.

Can the glance card be updated so the relative-time is accurate like the logook card?

Below is a quick example I had handy. If I let it sit longer the logbook relative time would continue to update whereas the glance time would not,.

This was on the current version of chrome and the user profile feature automatically close connection feature disabled.

Thanks
