in this new version I added the possibility to enable time highlight. If you enable this then every time the block is updated in the background, the time will briefly be highlighted. You can also set the highlight interval, i.e. for how long the time will stay highlighted. If you set this to something really short, the time will just briefly flash. If something longer, it will stay highlighted for that time.
Note: In the demo the interval is relatively long, set to 30s (to prevent server overload), so if you want to see it, you would have to wait 30s.
