How to do that?

Unix time stamp is in seconds since epoch right? You can convert it into milliseconds (by multiplying it by 1000) and passing it to the date constructor like this to convert it to a Date object.
new Date(unixtimestamp*1000)
Then you can use the Date APIs to get parts of the date.

unix timestamp has an accuration of second, so convert to milisecond and pass to Date constructor:
var d = new Date(timestamp * 1000)

As long as it's a valid date string, you should be able to get a Date object out of it using Date.parse().

I want to convert given Date time to local Date time, when input Date time and timeZone is given separately as below
Date -20220120080000 ('yyyymmddHHMMSS')
timezone string -("Australia/Perth")
How to convert above timezone to local Date time without using moment library ?
If you are able to use moment, this becomes pretty straightforward.
Check this working example.
let date = "20220120080000";
const format = "YYYYMMDDHHmmss";
let tz = "Australia/Perth";
const remoteTime = moment.tz(date, format, tz);
const localTime = moment(remoteTime).local();

I know there are numerous ways to go about this, but I'm dealing with date formatted as such:
"2021-01-06T16:24:34Z"
How do I convert this to a timestamp that represent post unix epoch with Javascript?
You just need to parse the date, then divide the resulting number by 1000 to have it in seconds.
To parse it, you just need to remove the T and the Z.
let dateString = "2021-01-06T16:24:34Z";
let dateForDateParsing = dateString.replace("T", " ").replace("Z", "");
console.log(dateForDateParsing);
let UnixTimestamp = Math.floor(new Date(dateForDateParsing) / 1000);
console.log(UnixTimestamp);
new Date("2021-01-06T16:24:34Z").getTime() / 1000

I'm using an api from CryptoCompare, here is the link
The response contains a field name published_on,I tried to use moment to convert to an appropriate date time format but it didn't work.
Does someone know the format or how to convert it to a normal datetime format.I'm using javascript
This is called Unix time stamp
console.log(+new Date()) // unix time stamp
console.log(new Date(1551929623 * 1000 )) //unix to normal date conversion
On side note: JS time stamp is in miliseconds where as a UNIX time stamps uses seconds. #JaromandaX thanks for info
This date is Unix time stamp. Since you are using moment, do the following to convert it to the date format
moment.unix(1551929623).format('DD/MM/YYYY')
Please change the format whatever suits you.

I want to get the Current Date object in UTC. I tried using new Date(), Date.now() etc. But they return the local time. How do I get the UTC date object?
I want the Date object, not string representation.
Just use new Date(new Date().toUTCString())
After converting to UTC, we have to again convert it into Date object if we need a Date Object.

I'm having a time in this format like
var time = "22:00:00"
I need to convert this into UTC time format like 1567890764
I'm using this one to convert time into UTC.
Math.floor(new Date().getTime() / 1000) //it return current UTC timestamp
how to pass the "time" variable and get UTC timestamp for that particular time?
You can just create UTC Timestamps with the full date.
You can use the .getTime() function of the Date object. You will get the milliseconds since 1970/01/01 and then divide it with 1000 to get the seconds.
let datestring = "2017-10-21 13:22:01";
let date = new Date(datestring);
console.log(date.getTime() / 1000); // will return 1508584921
You can also take a look at Moment.js which is great for handling Date and Time in Javascript.
EDIT:
If you want todays date 22:00:00 just init new Date and set the time like this:
let date = new Date();
date.setHours(22);
date.setMinutes(0);
date.setSeconds(0);
