How to prevent jQuery bootstrap ClockPicker to get minutes that are not divisible by 5

Question

I am using jQuery bootstrap ClockPicker and need to get only times that their minutes are divisible by 5. For example if user selects 13:08, the ClockPicker should select 13:05.

Answer 1

If you don't mind make changes into Clockpicker (i had to do it for IE), adds an unofficial option like "roundmodfive" in bootstrap-clockpicker.js:
1. change this

// Hours and minutes are selected
ClockPicker.prototype.done = function() {
    raiseCallback(this.options.beforeDone);
    this.hide();
    var last = this.input.prop('value'),
        value = leadingZero(this.hours) + ':' + leadingZero(this.minutes);
    if  (this.options.twelvehour) {
        value = value + this.amOrPm;
    }
...

2. By this

// Hours and minutes are selected
ClockPicker.prototype.done = function() {
    raiseCallback(this.options.beforeDone);
    this.hide();

    var last = this.input.prop('value');
    //Unofficial option added
    /*
        Just an explain:
            I like rounding. Thus, for example 43min => 45 and 42min => 40.
            The minutes are base 60, so you have to make modulus 60.
    */
    if (this.options.roundmodfive) {
        this.minutes = (Math.round(parseInt(this.minutes) / 5)) * 5 % 60;
    }

    var value = leadingZero(this.hours) + ':' + leadingZero(this.minutes);
    if  (this.options.twelvehour) {
        value = value + this.amOrPm;
    }
