If you want to convert your current time to another timezone lets say GMT or UTC then you can follow the following steps for javascript:
You can use moment-timezone lib.
const moment = require('moment-timezone')
const now = moment().format()
moment.tz(now, 'UTC').format()
moment.tz(now, 'GMT').format()

I have an UTC time from MySQL like this - "2023-02-18T06:00:00.000Z". I have to convert this into Locale time in ISO format.
I have used .toLocaleString() function, but it is giving me date time in readable format, I need the UTC time converted into Locale time in ISO format just like it saved in the MySql. How to get that?

I have a timepicker that allows the user to select a time. If they select 7:00pm how can I convert that to UTC 24H time?
If there is already an answer to this question and someone could direct me to it that would be great.
Since you tagged JavaScript and jQuery, I could guess you are using https://github.com/jonthornton/jquery-timepicker#timepicker-plugin-for-jquery? If so, try calling getTime method:
$('#my-timeicker-id').getTime(); // returns Javascript Date object
Check for your timepicker's API (e.g. https://github.com/jonthornton/jquery-timepicker#methods) for more.

In case you are using your own timepicker, you will have to implement it yourself. For learning purposes great, go for it! Otherwise don't reinvent the wheel and pick an existing solution.

I want to create a script in php, javascript or jquery which tells me when a post is posted like Facebook in facebook when we post a status it tells us posting time like 5 minute ago or so on. I have completed all other work.
Create a coloumn to the table where you save the post details as posted_at and have DATETIME as its data type,
Use $CurrentTime = date("Y-m-d H:i:s" ); and insert while you create the post i.e., insert
So while retrieving the data just find the difference between the posted time and current time by
$PostedTime = strtotime($FetchedData->posted_at) - strtotime(date("Y-m-d H:i:s" ));
Then you shall convert the difference time as per your wish.
You have to create function that will get one parameter "posted date" and it will calculate difference from today. it will generate string and return like "2 days ago/5 min ago" or date. it is depend on you.

I am working on an application to get historical stock data from yahoo finance csv api. I am having trouble creating a script that will get the current day and count back 23 weekdays (not counting weekends or holidays). The idea is that it will plug the two dates in at yahoo, get the historical data and then create a moving average. I am unsure how to do this using the date function though.
You could use the Moment.js library, if you are able to provide that to your page. You could use it to do something like this:
var today = moment();
var pastDate = today.subtract('days', 23);
// then do something with those two variables...
if you need them in a certain format before you pass them along, just call .format on them
getHistoricalData(today.format('YYYYMMDD'), pastDate.format('YYYYMMDD'));

Can anyone please explain me how to put a digital clock in my jsp page. I have to put two clock one for India and one for Switzerland.
How can this be possible ?
This website has a tutorial on using the Date.getTimezoneOffset() method which you'll be able to use to define the clock locally.
http://www.onlineaspect.com/2007/06/08/auto-detect-a-time-zone-with-javascript/
India is easy- one time zone for the whole country, and no daylight savings time.
India time is UTC+05:30.
Sweden observes dst between 2:00 am on the last Sunday in March and 3:00 am the last Sunday in October.
Sweden's offsets are UTC+1:00 during standard time, UTC+2:00 during dst.
Be sure to apply the dst changes in Sweden's time, which is easy to calculate from UTC.
