For Change color

I have a problem with a screen. In it I have a label with a red background color. With a timer I would like that color to turn green at a certain hour and minute. But when the time comes that color change doesn’t happen. If I exit the screen and reload it, the change is triggered. Not when the screen is active and the time comes.
Advice, please.

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select “Download Blocks as Image”. You might want to use an image editor to crop etc. if required. Then post it here in the community.
