How to properly implement this task?

Question

PHP

Hello !
Help to implement the task...
...We need to make a looped timer that runs on the server side, once every 15 minutes, and performs the task, and on the user side it displays how much time is left before the start of a new task execution, so I don’t know how to implement it? I thought with cron, but the question is how to connect the jq timer with cron...

Answer 1

And why should the timer be connected with the crown, and what are you going to connect there?
There is a cron that runs every 15 minutes, so you know the time when it will run, why bind anything somewhere? Count yourself from the current time how much is left before the desired interval. There is only 1 nuance - it is desirable to receive the time from the server, otherwise no one knows how the clock goes on the client machine.
