Question

need some help with adding extra time to current time

currentTime= new Date(); 
var hours2 = currentTime.getHours() + 4;
var minutes2 = currentTime.setMinutes(currentTime.getMinutes() + 30);

however it outputs as: 15:1455880112692PM and does not seem to be adding 4.5 hours? anyone have any ideas on this?

Answer 1

That’s because you are not getting the minutes, you are getting the Date object. The setMinutes method doesn’t return the minutes, it returns the Date object itself. Converting a Date object to a string to display it gives you the time in milliseconds since epoch.

First convert the time, so that you get a correct time that wraps over, and not something like 27:93 instead of 04:33.

currentTime = new Date();
currentTime.setHours(currentTime.getHours() + 4);
currentTime.setMinutes(currentTime.getMinutes() + 30);

Then you can get the hours and minutes from it:

var hours2 = currentTime.getHours();
var minutes2 = currentTime.getMinutes();

Instead of adding 4 hours and 30 minutes, you can add 270 minutes:

currentTime = new Date();
currentTime.setMinutes(currentTime.getMinutes() + 270);
