10s Countdown timer skips 1 or more seconds seemingly to catch up on 1.24 w/ sync_issues: fix.

[alexruffell]

Describe the bug Sync issues were causing my 10s countdown timer to sometimes start from 8s. I rarely, if ever, see it start from 10s but that was not an issue and actually more accurate as counting down 9 to 0 is 10 seconds anyway. After updating to 1.24 and adding the sync_issues: fix I am now seeing a more annoying issue where the timer often starts from 10s but it skips 9s and sometimes 7s. The issue is repeatable but it does not happen 100% of the times. I noticed the issue on my Win11 desktop.

In my use case, the actual time is not relevant as I use it to trigger an alarm that wakes up my kids and the trigger is on a 10s delay so I can turn it off if done by mistake. Once they are awake... they are awake... so it IS mission critical ;-)

Hmm I'll have to look into why this is.

Until I stop the timer from jumping around, you can use sync_issues: ignore. The timer will start counting down from 8 again, but you won't see the sync warning or this issue.
