Javascript Time Function Issues -

html5 is having trouble entering a text box and writing a javascript function that will ensure that the entered Time is not less than 30 minutes from the present time. How to get the current date mainly, my biggest concern is whether it will be as simple as the date. Now add (30 minutes) and then 30 minutes?

i have recently used moment.js for a project .. is that really something good Methods of time ...

  //// Get today today vir now = (new date ()); /// In a JavaScript Date Object view, look for ways that they try to list console.log (Object.quiz (now));  

moment. Give Google a Google, making the difference between 2 dates easier.
