It's hard enough to fake as much false data as possible.The last note recorded how to get a random license plate. This note recorded how to get a random time.That's not so much nonsense, just code it

//    Gets a random number in a specified range
var getRangeRandomNumber = function(num1,num2){ 
    num1 = Number.isInteger(num1) ? num1: 0;
    num2 = Number.isInteger(num2) ? num2: 0;
    var minNum=Math.min(num1,num2),maxNum=Math.max(num1,num2);
    return Math.round(Math.random() * (maxNum - minNum)) + minNum;
}; 
//    Date extension: formatted date
var dateExtendFormat = function(date, format) {
    var o = {
        "M+": date.getMonth() + 1, 
        "d+": date.getDate(), 
        "H+": date.getHours(), 
        "m+": date.getMinutes(), 
        "s+": date.getSeconds(), 
        "q+": Math.floor((date.getMonth() + 3) / 3), 
        "S": date.getMilliseconds() 
    }
    if (/(y+)/.test(format)) format = format.replace(RegExp.$1, (date.getFullYear() + "").substr(4 - RegExp.$1.length));
    for (var k in o) {
        if (new RegExp("(" + k + ")").test(format)) {
            format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k] : ("00" + o[k]).substr(("" + o[k]).length));
        }
    }
    return format;
};
//    Get Random Time for a Specified Range, Dependent on Method getRangeRandomNumber,dateExtendFormat
var getRangeRandomDate=function(date1,date2,format){
    var date1ValueOf=new Date(date1).valueOf(),date2ValueOf=new Date(date2).valueOf();
    if(isNaN(date1ValueOf)&&isNaN(date2ValueOf)){
        date1ValueOf=0;
        date2ValueOf=new Date().valueOf();
    }
    else{
        if(isNaN(date1ValueOf))date1ValueOf=0;
        if(isNaN(date2ValueOf))date2ValueOf=0;
    }
    var retDate=new Date(getRangeRandomNumber(Math.abs(date1ValueOf-date2ValueOf)) + Math.min(date1ValueOf,date2ValueOf));
    if(format){
        retDate=dateExtendFormat(retDate,format);
    }
    return retDate;
};

- Stick in the test code

console.log("*********************************************************Test 1: Yes Date type*********************************************************");
for(var i=0;i<5;i++){
    console.log(getRangeRandomDate());
}    
console.log("*********************************************************Test 2: Returns the string time in the specified format*********************************************************");
for(var i=0;i<5;i++){
    console.log(getRangeRandomDate(undefined,"2019-11-07","yyyy-MM-dd HH:mm:ss"));
}
console.log("*********************************************************Test 3: Returns the string time in the specified format*********************************************************");
for(var i=0;i<5;i++){
    console.log(getRangeRandomDate("2019-11-07","I am not the time","yyyy-MM-dd HH:mm:ss.S"));
}
console.log("*********************************************************Test 4: Returns the string time in the specified format*********************************************************");
for(var i=0;i<5;i++){
    console.log(getRangeRandomDate("2019-11-07","2019-11-06 23:59:59","HH:mm:ss"));
}

Take a look at the test results

If it weren't for some nonsense, it would be short enough...But there's no doubt about this, so let's finish!
