Add time to the date value

Question

I am using a jQuery plugin named mobiscroll to select a date, but the problem is that I also need to add to the result plus 15 minutes.

I have a function p(j), which returns 08/28/2012 12:15 - 12:15 (or only 08/28/2012 12:15 - as convenient), but instead i need 12:15 - 12:30. Are there any ideas?

@Sirko there only compressed jquery, so need to do some thing with this string — NoNameZ, Aug 28 '12 at 09:13
`08/28/2012 12:15 - 12:15` it is a string or a date object ? — Genosite, Aug 28 '12 at 09:17

What about string manipulation?

var dateStr = p(j), //08/28/2012 12:15 - 12:15
    timeStrSlice = dateStr.split(' ')[1].split(':'),
    h = parseFloat(timeStrSlice[0]),
    m = parseFloat(timeStrSlice[1]);

var nh = h,
    nm = m + 15;

if(nm > 60) {
   nh++;
   nm = 0;
}
if(nh > 24) {
   nh = 0;
}

var result = h + ":" + m + " " + nh + ":" + nm; // 12:15 12:30

Your code can't work look line 7 : `nm = m + 15` nm is not reset – Genosite Aug 28 '12 at 09:27
What do you mean its not reset? have you noticed `,` (comma) sign at the end of line 6? – Aug 28 '12 at 09:52
if `m = 60` with `nm = m + 15` nm = 75 so `nm > 60` its impossible – Genosite Aug 28 '12 at 10:02
Oh sorry, you are right. I added `nm = 0` line after increasing `nh`. – Aug 28 '12 at 10:07

According to the mobiscroll documentation setDate works with a Date object.

See this link on how to work with date objects in javascript. You don't need to do any string manipulations.

After you have the right date use the .scroller('setDate',newDate,true);

Date d = new Date(2012,08,28); d.setHours(12, 30, 0, 0);

See if this works for you:

var now = new Date();
//add 15 minutes to now
var out = new Date(now).setMinutes(now.getMinutes()+15)
