Convert UTC date time to local date time

Question

From the server I get a datetime variable in this format: 6/29/2011 4:52:48 PM and it is in UTC time. I want to convert it to the current user’s browser time us

Answer 1

For the TypeScript users, here is a helper function:

// Typescript Type: Date Options
interface DateOptions {
  day: 'numeric' | 'short' | 'long',
  month: 'numeric',
  year: 'numeric',
  timeZone: 'UTC',
};

// Helper Function: Convert UTC Date To Local Date
export const convertUTCDateToLocalDate = (date: Date) => {
  // Date Options
  const dateOptions: DateOptions = {
    day: 'numeric',
    month: 'numeric',
    year: 'numeric',
    timeZone: 'UTC',
  };

  // Formatted Date (4/20/2020)
  const formattedDate = new Date(date.getTime() - date.getTimezoneOffset() * 60 * 1000).toLocaleString('en-US', dateOptions);
  return formattedDate;
};
