A string with "2019-04-29 06:12:06" does not indicate the time zone. If you add a 'Z' at the end, the built in Date function understands that the time is in UTC.
const cache_time = "2019-04-29 06:12:06";
const date = new Date ( cache_time + "Z" );
console.log("UTC TIME", date.toISOString())
console.log("LOCAL TIME", date.toLocaleString() );

@SyedMehtabHassan There is no need to call
Date.parse since Date will parse the argument since it is a string.

@SyedMehtabHassan Ok :) Happy editing!
Use the Moment.js libary:
date = new Date("2019-04-29 06:12:06Z");
var withoutUTC = moment(date).toString();
var withUTC = moment.utc(date).toString();
console.log(withoutUTC)
console.log(withUTC)<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.1/moment.js"></script>

It's mean this date 2019-04-29 06:12:06 so when time was 06:12:06 on my computer my time was a 03:12:06 right ?

No, this gives a date and time in the users time-zone. Add a 'Z' to the end of the timestamp, and Date will understand that it is UTC and will display it in the users timezone.

@user3348410 what output you expect ?
user3348410
I understand that: it's give me difference with utc time and my local time. so +03.00 hours. Everything well. But how i can show it like 2019-04-29 ' here sum of this difference time' eg: if utc is 12:00 and difference 3 hour i would show it like: 2019-04-29 15:00

Use moment.js to convert utc to local time.In your case:
moment().utc("2019-04-29 06:12:06").local().format()

It's give me "2019-04-29T18:40:24+03:00" something like this. i didn't understand what is this mean

what date time object you passed to moment?
Or you can use spacetime.js, which is based on moment.js and takes into consideration also timezones. const localTimeDate = spacetime().now().format();
