function secondsToHms(d) { d = Number(d); var h = Math.floor(d / 3600); var m = Math.floor(d % 3600 / 60); var s = Math.floor(d % 3600 % 60); return (‘0’ + h).slice(-2) + “:” + (‘0’ + m).slice(-2) + “:” + (‘0’ + s).slice(-2); } document.writeln(‘secondsToHms(10) = ‘ + secondsToHms(10) + ‘<br>’); document.writeln(‘secondsToHms(30) = ‘ … Read more

What is the maximum value of a number in Lua?

as compiled by default, the Number is a double, on most compilers that’s an IEEE 64-bit floating point. that means 10bit exponent, so the maximum number is roughly 2^1024, or 5.6e300 years. that’s a long time. now, if you’re incrementing it, you might be more interested in the integer range. the 52-bit mantissa means that … Read more

Time manipulation in ruby

A Time is a number of seconds since an epoch whereas a DateTime is a number of days since an epoch which is why adding 1 to a DateTime adds a whole day. You can however add fractions of a day, for example d = DateTime.now d + Rational(10, 86400) Will add 10 seconds to … Read more

Date Time Formats in Python

That extra .000 is micro seconds. This will convert a date string of a format to datetime object. import datetime d1 = datetime.datetime.strptime(“2013-07-12T07:00:00Z”,”%Y-%m-%dT%H:%M:%SZ”) d2 = datetime.datetime.strptime(“2013-07-10T11:00:00.000Z”,”%Y-%m-%dT%H:%M:%S.%fZ”) Then convert them into any format depending on your requirement, by using: new_format = “%Y-%m-%d” d1.strftime(new_format)

How to check a timeperiod is overlapping another time period in java

There is a simple solution, expressed here as a utility method: public static boolean isOverlapping(Date start1, Date end1, Date start2, Date end2) { return start1.before(end2) && start2.before(end1); } This code requires there to be at least one millisecond to be shared between the two periods to return true. If abutting time periods are considered to … Read more

How to make a ticking clock (time) in AngularJS and HTML

Just trying to improve Armen’s answer. You can use the $interval service to setup a timer. var module = angular.module(‘myApp’, []); module.controller(‘TimeCtrl’, function($scope, $interval) { var tick = function() { $scope.clock = Date.now(); } tick(); $interval(tick, 1000); }); <script src=”https://ajax.googleapis.com/ajax/libs/angularjs/1.2.11/angular.min.js”></script> <div ng-app=”myApp”> <div ng-controller=”TimeCtrl”> <p>{{ clock | date:’HH:mm:ss’}}</p> </div> </div>
