[Suggestion] Timer functions

[marshular]

Is your feature request related to a problem? Please describe. My feature is not related to any problem, but I would like to see some type of time timer function.

Describe the solution you'd like Examples: lib.timer.start(name, time) lib.timer.end(name) lib.timer.pause(name) lib.timer.change(name, time) lib.timer.onend(name, function() -- do something end)

Additional context N/A
