Convert JS date time to MySQL datetime

Does anyone know how to convert JS dateTime to MySQL datetime? Also is there a way to add a specific number of minutes to JS datetime and then pass it to MySQL datetime?

Answer

While JS does possess enough basic tools to do this, it's pretty clunky.

/**
 * You first need to create a formatting function to pad numbers to two digits…
 **/
function twoDigits(d) {
    if(0 <= d && d < 10) return "0" + d.toString();
    if(-10 < d && d < 0) return "-0" + (-1*d).toString();
    return d.toString();
}

/**
 * …and then create the method to output the date string as desired.
 * Some people hate using prototypes this way, but if you are going
 * to apply this to more than one Date object, having it as a prototype
 * makes sense.
 **/
Date.prototype.toMysqlFormat = function() {
    return this.getUTCFullYear() + "-" + twoDigits(1 + this.getUTCMonth()) + "-" + twoDigits(this.getUTCDate()) + " " + twoDigits(this.getUTCHours()) + ":" + twoDigits(this.getUTCMinutes()) + ":" + twoDigits(this.getUTCSeconds());
};
Answer
var date;
date = new Date();
date = date.getUTCFullYear() + '-' +
    ('00' + (date.getUTCMonth()+1)).slice(-2) + '-' +
    ('00' + date.getUTCDate()).slice(-2) + ' ' + 
    ('00' + date.getUTCHours()).slice(-2) + ':' + 
    ('00' + date.getUTCMinutes()).slice(-2) + ':' + 
    ('00' + date.getUTCSeconds()).slice(-2);
console.log(date);

or even shorter:

new Date().toISOString().slice(0, 19).replace('T', ' ');

Output:

2012-06-22 05:40:06

For more advanced use cases, including controlling the timezone, consider using http://momentjs.com/:

require('moment')().format('YYYY-MM-DD HH:mm:ss');

For a lightweight alternative to , consider https://github.com/taylorhakes/fecha

require('fecha').format('YYYY-MM-DD HH:mm:ss')
Answer

I think the solution can be less clunky by using method toISOString(), it has a wide browser compatibility.

So your expression will be a one-liner:

new Date().toISOString().slice(0, 19).replace('T', ' ');

The generated output:

"2017-06-29 17:54:04"

Answer

JS time value for MySQL

var datetime = new Date().toLocaleString();

OR

const DATE_FORMATER = require( 'dateformat' );
var datetime = DATE_FORMATER( new Date(), "yyyy-mm-dd HH:MM:ss" );

OR

const MOMENT= require( 'moment' );
let datetime = MOMENT().format( 'YYYY-MM-DD  HH:mm:ss.000' );

you can send this in params its will work.

Answer

For arbitrary date string,

// Your default date object  
var starttime = new Date();
// Get the iso time (GMT 0 == UTC 0)
var isotime = new Date((new Date(starttime)).toISOString() );
// getTime() is the unix time value, in milliseconds.
// getTimezoneOffset() is UTC time and local time in minutes.
// 60000 = 60*1000 converts getTimezoneOffset() from minutes to milliseconds. 
var fixedtime = new Date(isotime.getTime()-(starttime.getTimezoneOffset()*60000));
// toISOString() is always 24 characters long: YYYY-MM-DDTHH:mm:ss.sssZ.
// .slice(0, 19) removes the last 5 chars, ".sssZ",which is (UTC offset).
// .replace('T', ' ') removes the pad between the date and time.
var formatedMysqlString = fixedtime.toISOString().slice(0, 19).replace('T', ' ');
console.log( formatedMysqlString );

Or a single line solution,

var formatedMysqlString = (new Date ((new Date((new Date(new Date())).toISOString() )).getTime() - ((new Date()).getTimezoneOffset()*60000))).toISOString().slice(0, 19).replace('T', ' ');
console.log( formatedMysqlString );

This solution also works for Node.js when using Timestamp in mysql.

@Gajus Kuizinas's first answer seems to modify mozilla's toISOString prototype

Answer

The venerable DateJS library has a formatting routine (it overrides ".toString()"). You could also do one yourself pretty easily because the "Date" methods give you all the numbers you need.

Answer

Full workaround (to mantain the timezone) using @Gajus answer concept:

var d = new Date(),
    finalDate = d.toISOString().split('T')[0]+' '+d.toTimeString().split(' ')[0];
console.log(finalDate); //2018-09-28 16:19:34 --example output
Answer

new Date().toISOString().slice(0, 10)+" "+new Date().toLocaleTimeString('en-GB');

100% working

I have given simple JavaScript date format examples please check the bellow code

var data = new Date($.now()); // without jquery remove this $.now()
console.log(data)// Thu Jun 23 2016 15:48:24 GMT+0530 (IST)

var d = new Date,
    dformat = [d.getFullYear() ,d.getMonth()+1,
               d.getDate()
               ].join('-')+' '+
              [d.getHours(),
               d.getMinutes(),
               d.getSeconds()].join(':');

console.log(dformat) //2016-6-23 15:54:16

Using momentjs

var date = moment().format('YYYY-MM-DD H:mm:ss');

console.log(date) // 2016-06-23 15:59:08

Example please check https://jsfiddle.net/sjy3vjwm/2/

Answer

The easiest correct way to convert JS Date to SQL datetime format that occur to me is this one. It correctly handles timezone offset.

const toSqlDatetime = (inputDate) => {
    const date = new Date(inputDate)
    const dateWithOffest = new Date(date.getTime() - (date.getTimezoneOffset() * 60000))
    return dateWithOffest
        .toISOString()
        .slice(0, 19)
        .replace('T', ' ')
}

toSqlDatetime(new Date()) // 2019-08-07 11:58:57
toSqlDatetime(new Date('2016-6-23 1:54:16')) // 2016-06-23 01:54:16

Beware that @Paulo Roberto answer will produce incorrect results at the turn on new day (i can't leave comments). For example:

var d = new Date('2016-6-23 1:54:16'),
    finalDate = d.toISOString().split('T')[0]+' '+d.toTimeString().split(' ')[0];
console.log(finalDate); // 2016-06-22 01:54:16 

We've got 22 June instead of 23!

Answer
var _t = new Date();

if you want UTC format simply

_t.toLocaleString('indian', { timeZone: 'UTC' }).replace(/(\w+)\/(\w+)\/(\w+), (\w+)/, '$3-$2-$1 $4');

or

_t.toISOString().slice(0, 19).replace('T', ' ');

and if want in specific timezone then

_t.toLocaleString('indian', { timeZone: 'asia/kolkata' }).replace(/(\w+)\/(\w+)\/(\w+), (\w+)/, '$3-$2-$1 $4');

I'm using this long time and it's very helpful for me, use as you like

Date.prototype.date=function() {
    return this.getFullYear()+'-'+String(this.getMonth()+1).padStart(2, '0')+'-'+String(this.getDate()).padStart(2, '0')
}

Date.prototype.time=function() {
    return String(this.getHours()).padStart(2, '0')+':'+String(this.getMinutes()).padStart(2, '0')+':'+String(this.getSeconds()).padStart(2, '0')
}

Date.prototype.dateTime=function() {
    return this.getFullYear()+'-'+String(this.getMonth()+1).padStart(2, '0')+'-'+String(this.getDate()).padStart(2, '0')+' '+String(this.getHours()).padStart(2, '0')+':'+String(this.getMinutes()).padStart(2, '0')+':'+String(this.getSeconds()).padStart(2, '0')
}

Date.prototype.addTime=function(time) {
    var time=time.split(":")
    var rd=new Date(this.setHours(this.getHours()+parseInt(time[0])))
    rd=new Date(rd.setMinutes(rd.getMinutes()+parseInt(time[1])))
    return new Date(rd.setSeconds(rd.getSeconds()+parseInt(time[2])))
}

Date.prototype.addDate=function(time) {
    var time=time.split("-")
    var rd=new Date(this.setFullYear(this.getFullYear()+parseInt(time[0])))
    rd=new Date(rd.setMonth(rd.getMonth()+parseInt(time[1])))
    return new Date(rd.setDate(rd.getDate()+parseInt(time[2])))
}

Date.prototype.subDate=function(time) {
    var time=time.split("-")
    var rd=new Date(this.setFullYear(this.getFullYear()-parseInt(time[0])))
    rd=new Date(rd.setMonth(rd.getMonth()-parseInt(time[1])))
    return new Date(rd.setDate(rd.getDate()-parseInt(time[2])))
}

and then just:

new Date().date()

which returns current date in 'MySQL format'

for add time is

new Date().addTime('0:30:0')

which will add 30 minutes.... and so on
