Is there a timestamp or way to trigger generation of a timestamp of the last time any tag properties including custom properties and properties of alarms for that tag have been changed? (but not the value)

I have some perspective views and scripts that modify tags which I could easily make update a custom property, but not sure how I could determine if a property is modified from the designer.

Updated title to be more clear hopefully.

Still looking to do this, but not sure it will be possible. Any way to trigger a script when anything in the tag configuration for a specific tag changes?

Not through direct scripting. This would be possible with a custom module that registers a TagActorFactory that registers “interest” in all the tag properties you care about.

Thanks, appreciate the response. That sounds quite a bit over my head, and probably more work than what I was trying to do is even worth.
