Need programmable timer from php

Hi, I have a web-based php/mysql booking system. I need to include alarms/timers that can handle intervals of between one to two hours between being set, and firing. For example, an appointment is initiated, and I need a notifcation to pop up 70mins later regardless of what else the user does with the application in the meantime.

Can I use the chron daemon on the server, somehow?

The server is linux, and users are on windows laptops running firefox.

Looking for either third party solutions or coding suggestions
Thanks.

"if the next job item checks for an outstanding or equals to situation then to move on to the next item." should read "if the next job item checks for an outstanding or equals to situation then open that work item or if not either of the above, move on to the next item."
