How to make scheduled tasks in Opencart on time (on an alarm clock)?

Question

opencart

I understand that you can send SMS immediately when placing orders. In this case, it turns out that the initiator of the call to the SMS sending function is the buyer himself.
And here's how to call the execution of a function for a certain time, I'll never know.
I need to send information about orders by SMS to the collector at 17:00.
Pts I hope for your help, gentlemen pros!
PS We are talking about Opencart 2.3, but I will accept the answer for any version. Thank you!

The answer came unexpectedly. In the hosting admin panel (timeweb.ru) there was an option "Crontab", which allows you to set up a PHP script call at the right time and at the right interval.
