Max min timepicker

Hello!
Please help with the code
I want to choose time with picker
https://framework7.io/docs/picker.html
It is very convenient!

I did this:

var pickerDescribe = app.picker.create({
    inputEl: '#demo-picker-describe',
    rotateEffect: false,
    routableModals: false,
    toolbarCloseText: 'Готово',
    formatValue: function (values, displayValues) {
        return values[0] + ':' + values[1];
    },
    cols: [
        // Hours
        {
            onChange: function (picker, country) {



            },
            values: (function () {
                
   
                var arr = [];
                for (i=0; i <= 23; i++) {
                    arr.push(i);
                }
                return arr;
            })(),
},
// Divider
        {
            divider: true,
            content: ':'
},
// Minutes
        {
            values: (function () {
                var arr = [];
                for (var i = 0; i <= 59; i += 10) {
                    arr.push(i < 10 ? '0' + i : i);
                }
                return arr;
            })(),
}
],
    on: {
        change: function (picker, values, displayValues) {
            var n_today = new Date();



        },
    }
});

But I really need to choose the maximum and minimum time.

Help write such a function
