If you have a date string in JavaScript that includes a 'Z' character (indicating a UTC timestamp), and you want to remove the 'Z' and work with the local time instead, you can do the following: In this example, we: Parse the input date string using new Date(dateString) to create a Date object. Calculate the local time by adding the time zone offset (in minutes) multiplied by 60,000 milliseconds to the UTC timestamp. The resulting localDate object will represent the date and time in the local time zone.
