How to use the appium-ios-device.utilities.getDeviceTime function in appium-ios-device

commands.getDeviceTime = async function getDeviceTime (format = MOMENT_FORMAT_ISO8601) {
  log.info('Attempting to capture iOS device date and time');
  if (this.isRealDevice()) {
    const { timestamp, utcOffset } = await utilities.getDeviceTime(this.opts.udid);
    return moment.unix(timestamp).utcOffset(utcOffset).format(format);
  } else {
    return await iosCommands.general.getDeviceTime.call(this, format);
  }
};
