Pause or unpause a timer. A paused timer does not invoke its callback when its time expires. Unpausing a timer may cause the callback to be invoked almost immediately if enough time has passed.

Pausing a timer is useful to avoid the callback to be called for a short time.

If {paused} evaluates to a non-zero Number or a non-empty String, then the timer is paused, otherwise it is unpaused. See non-zero-arg.

Can also be used as a method:

GetTimer()->timer_pause(1)

only available when compiled with the +timers feature
