clocktick

Clock-accurate timeout for Node.js and browser. Basically it is identical to setTimeout, but it triggers callback function precisely on the next second.

example

Tick at (hh:mm:ss:ms)
(compare to your computer's clock..)

var Ractive = require('ractive')
var tick = require('clocktick')

var ractive = new Ractive({
  el: '#ractive-container',
  template: '{{timestamp}}'
})

tick(updateTimestamp)

function updateTimestamp () {
  var now = new Date()

  var hours = ('0' + now.getHours()).slice(-2)
  var minutes = ('0' + now.getMinutes()).slice(-2)
  var seconds = ('0' + now.getSeconds()).slice(-2)
  var milliseconds = ('00' + now.getMilliseconds()).slice(-3)

  var timestamp = hours + ':' + minutes + ':' + seconds + ':' + milliseconds

  ractive.set('timestamp', timestamp)
  tick(updateTimestamp)
}
