Change Multiple Records Values Based on Current Time

I have a Users table that has a on duty, radio check, and current status value. Our shifts are in 8 hour blocks. Is it possible to change the values for every user at 0600, 1400 and 2200 every day?

I was just answering that question on the Post before yours. The answer is yes and you will find details here Create a thing at regular intervals (eg daily)?
