JQ counts down every 10 minutes

Question

The project requires a draw every 10 minutes, which needs to be synchronized with the server time to prevent cheating

My idea is to use ajax to get the server time every 10 seconds, and then use JQ to compare the countdown.

For example, the time I retrieved is 18:02

The time I drew the lottery is 18:09 18:19 18:29 and so on

Then the logic of JQ should be How to write it? The countdown time on the front-end page always cycles from 10 minutes to 09:59 09:58. The display like this

needs to be calculated based on the server time. How to write this logic
