Days, Hours, Minutes and Seconds
Under the set time drop-down you can select the amount of time to set. This will be reflected in the Time in seconds remaining. The timer is set up to do all the calculations in seconds, using Time.deltaTime. This keeps it frame rate independent when being used of many different systems
Note – Free version limits to hours, minutes and seconds.
Events
There are two built-in custom events for the timer, which run on timer start, or at timer end. Simply link up your object, make sure your custom function is set to Public and select it from the event handler.
Note – Free version only has OnTimerEnd.
