Tried that to no avail yesterday, but comparing few versions I think I have an idea. I'm going to test it today to see if that change will fix this problem.

UPDATE. Yes, that change fixed the problem.

Here is what I changed:

var format = function (date) {
                        if (date) {
                            if (!pickTime) {
                                if (isEndDate && !onlyFutureDates) {
                                    date = date.hours(23).minutes(59).seconds(59).milliseconds(997);
                                    date = date.format("YYYY-MM-DD HH:mm:ss.SSS").toString();
                                } else {
                                    date = date.hours(0).minutes(0).seconds(0).milliseconds(0);
                                    date = date.format("YYYY-MM-DD HH:mm:ss").toString();
                                }
                            }
                            else
                            {
                                date = date.format("YYYY-MM-DD HH:mm:ss.SSS").toString();
                            }
                        }
                        return date;
                    };

In my previous version the else case was missing and I was using T as a format string. I'm going to verify if that change didn't cause any undesired effects.
