Question

i have this datetime format:

Oct 31, 2012 08:59:52

i would like to re-calculate the datetime incremented (for example) of 2 hours or 50 minutes plus how can i do that?

i need to return the same datetime format showed above and not a timestamp!

Answer 1

var date = new Date("Oct 31, 2012 08:59:52");
var timeInMillis = date.getTime();

Now that you have time in milliseconds, you can just add the time you want in millis.

Eg: 2 hours? So, 2*60*60*1000 + timeInMillis

var newDate = new Date(2*60*60*1000 + timeInMillis);

If you want to convert your newDate into the original format, which is a long process, you can some guidance from here:

Where can I find documentation on formatting a date in JavaScript?
