Dayjs behave wired between mobile and web application

I am using this function to parse wall time of future event to user local timezone:

export const parseGatheringDate = (
  timeZone: string,
  gatheringData: {
    date: string;
    time: string;
    timeZone: string;
  }
) => {
  const eventDateTime = `${gatheringData.date}T${gatheringData.time}:00`;

  const gathering = dayjs.tz(eventDateTime, gatheringData.timeZone);

  const eventInLocalTime = gathering.tz(timeZone);

  const formattedEventTime = eventInLocalTime.format("YYYY-MM-DD HH:mm");

  return formattedEventTime;
};

And on web I am getting:

2024-08-21 02:00
2024-08-21 08:00

Which are correct values.
But on IOS simulator in react-native for the same code I am getting:

2024-08-21 06:44
2024-08-21 06:44

Test code is:

console.log(
      "DATE 1",
      parseGatheringDate("Europe/Belgrade", {
        date: "2024-08-21",
        time: "08:00",
        timeZone: "Europe/Belgrade",
      })
    );
    console.log(
      "DATE 2",
      parseGatheringDate("America/New_York", {
        date: "2024-08-21",
        time: "08:00",
        timeZone: "Europe/Belgrade",
      })
    );
