A very simple ticker that emits tick events at a clock-synchronised, self-adjusting interval.
- It ticks at the specified interval.
- It keeps itself synchronised with the system clock.
- .. more ticks.
npm install --save clock-tickr
Create a ClockTickr instance, with an optional tick interval in ms (default is 1000) and start it. See below.
const ClockTickr = require('clock-tickr')
let tickr = new ClockTickr({ interval: 250 })
tickr.on('tick', (tick) => {
console.log(tick)
if (Math.abs(tick.drift) > 20) {
console.log('Did you travel in time?')
}
})
tickr.start()results in (when you change the system time while running)
