Use the below. It takes the local datetime and converts it to UTC using the timezone. You do not need to create it function.

ZonedDateTime nowUTC = ZonedDateTime.now(ZoneOffset.UTC);
System.out.println(nowUTC.toString());

If you need to obtain the LocalDateTime part of the ZonedDateTime then you can use the following.

nowUTC.toLocalDateTime();

Here is a static method i use in my application to insert UTC time in mysql since i cannot add a default value UTC_TIMESTAMP to a datetime column.

public static LocalDateTime getLocalDateTimeInUTC(){
    ZonedDateTime nowUTC = ZonedDateTime.now(ZoneOffset.UTC);

    return nowUTC.toLocalDateTime();
}
