Create Date Format In JavaScript
In JavaScript, the date object is based on a timestamp of milliseconds elapsed since the epoch.
The date output will use the time zone of the local device which is normally the web browser. The date time string is simplified from the ISO 8601 calendar date extended format. The format is YYYY-MM-DDTHH:mm:ss.sssZ.
A date object is created via the date constructor and built-in functions can manipulate the object output. ISO 8601 is maintained by the International Organization for Standardization. The standard was published in 1988 and last updated in 2022.
