Highight cell based on current time

Working on an hourly To-Do list. I have a column (H) with the list hour (on the Hr) starting with 5am all the way until 11pm.For Example:

5:00 AM6:00 AM 7:00 AM8:00 AM

and so on....

I would like the 7:00 AM cell be highlighted when the current time is between 7-7:59 AM. The then the next cell once it hits 8 and so on.

Thank you and let me know what you think?
