Countdown block - Recurring countdown loop not working properly

[andeng1106]

Describe the bug

• Sample test: I set 10:55AM as the time then the countdown ended. I went back again 11:55AM and expected the 1 minute countdown to count again on frontend (don't mind the editor). But instead, it counted on 11:56AM.
• Tried again another loop but it starts counting on 12:57PM
• Issue: Every loop it adds +1 minute before the countdown starts again
• Issue in frontend only

Here's a sample test page: https://gambitsandbox.instawp.xyz/andrea/countdown-recurring/

To Reproduce
Steps to reproduce the behavior:

1. Add a new page
2. Add a Countdown block
3. Add these settings:
   Time: 10:55 AM
   Date: Oct 2, 2024
   Countdown Duration: 1 minute
   Restart after no. of hours: 1 hour
4. Return at 11:55AM
5. Check if the countdown started to count again
6. See that it starts counting on 11:56AM
7. Return at 12:55PM
8. Repeat step 5
9. See that it starts counting on 12:57PM

Expected behavior

• Countdown should count again on 11:55AM / 12:55PM / 1:55PM and so on as long as 1 hour loop
• Should not add +1 minute on each loop

Actual Behavior / Issue:
It didn't count on 11:55AM, instead the Countdown counts on 11:56AM
After another loop at 12:55PM, it counts on 12:57PM
