convert gmt to australian western daylight time in typescript

To convert GMT to Australian Western Daylight Time (AWDT) in TypeScript, you can use the toLocaleString() method of the Date object, along with the 'en-AU' locale for Australia and the 'Australia/Perth' timezone for Western Australia.

Here's an example code snippet:

index.ts
// set the time in GMT
const dateInGMT = new Date('2022-03-20T10:30:00Z');

// convert to Australian Western Daylight Time
const options = { 
  timeZone: 'Australia/Perth',
  timeZoneName: 'short'
};
const dateInAWDT = dateInGMT.toLocaleString('en-AU', options);

console.log(dateInAWDT); // output: 20/03/2022, 6:30:00 pm AWDT

In this example, we set the time to 10:30 AM in GMT on March 20, 2022. Then we use the toLocaleString() method with the 'en-AU' locale and the 'Australia/Perth' timezone, which gives us the output in the format "DD/MM/YYYY, H:mm:ss a zzz", where "zzz" represents the timezone abbreviation. The timeZoneName: 'short' option displays the abbreviated timezone name, which in this case is "AWDT" for Australian Western Daylight Time.

Note that the output format can vary depending on the locale and timezone settings, but the underlying conversion logic remains the same.
