[SOLVED] How to Change Date Format from UTC Timezone to Any Required Timezone

In Drupal, usually the date field value is saved in the database in UTC timezone format. One of our requirements for a project was to show the date in the site's timezone format. So we generated a general function to convert date in UTC timezone to any required timezone and format it.

Just use the below function to convert date in UTC timzone to a given timezone and the format date using a valid timestamp,

/**
 * Function to get date/time on user's timezone
 * @param  int $timestamp
 *  Timestamp to be converted to date
 * @param string timezone
 *  Timezone to which date is to be converted
 * @param  string $format
 *  Format to which date to convert
 * @return string
 *  Formatted date.
 */
function get_date_on_given_timezone($timestamp, $new_timezone, $format = 'd/m/Y H:i:s') {
  if (!empty($timestamp)) {
    // Database timezone.
    $db_timezone = 'UTC';
    $date_object = new DateObject($timestamp, new DateTimeZone($db_timezone));
    // Convert from the database time zone to site's time zone.
    $date_object->setTimezone(new DateTimeZone($new_timezone));
    $new_date = date_format_date($date_object, 'custom', $format);
    return $new_date;
  }
}

Hope this snippet is helpful for you.
