now-immediate

now-immediate

Package provide function, that returns timestamp in ms (like Date.now()).

But after 1st usage, on this event loop, function will return 1st answer.

Example:

var nowIm = require('now-immediate');
console.log('Start');
console.log('Date.now(): '+Date.now()+'\tnowIm(): '+nowIm());
for(var i = 0; i < 10000000; i++){
  /123/.test(i);
}
console.log('Finish');
console.log('Date.now(): '+Date.now()+'\tnowIm(): '+nowIm());
setImmediate(function(){
  console.log('Next loop');
  console.log('Date.now(): '+Date.now()+'\tnowIm(): '+nowIm());
});

The result will be:

Start
Date.now(): 1460683017773       nowIm(): 1460683017773
Finish
Date.now(): 1460683019252       nowIm(): 1460683017773
Next loop
Date.now(): 1460683019254       nowIm(): 1460683019254

In some case, you may need this behaviour. Also it X16+ just faster, than Date.now().
