Im developing (noob level :sleeping: ) a website and I want timer. Timer that I can set a time to start and duration to end, much like a counter. Example: Time Start is 8:15:32 for 8 hours, it will display a counter until 8 hours will pass with the started time. Also, users might as well log out and log in again and I want the timer to be following the right countdown. Any thoughts on this?
