bower install timekeeper
var tk = require'timekeeper';var time = 1330688329321;tkfreezetime;// The time hasn't changed at all.var date = ;var ms = Datenow;tkreset; // Reset.
var tk = require'timekeeper';var time = 1893448800000; // January 1, 2030 00:00:00tktraveltime; // Travel to that date.setTimeout// `time` + ~500 ms.var date = ;var ms = Datenow;tkreset; // Reset.500;
var tk = require'timekeeper';var time = 1893448800000; // January 1, 2030 00:00:00assertFalsetkisKeepingTime;tktraveltime;assertTruetkisKeepingTime;
