When you would like a timer callback to fire based on the timestamp of the data you are processing - the timestamp of the data stream when you created the timer rather than real time.
When you are processing older time series data may need to do a particular action for every one of a specific timespan of data.
// create new manager starting at timestamp 0var manager = 0;// create a timeout that should fire when i set the time to >= 1000manager// it is now 1000 ms since i startedmanager;// next tick prints// i fired !
module.exports is a function it returns a new object to manager timers.
