             * Leveraging the input parameters 'DOB' and 'DateTimeNowUTC', develop logic to set the output parameters 'Age' and 'Next Birthday'.

             * 

             * *Notes*

             * 1. Both age and next birthday should be calculated in AEST (TimeZoneID 'AUS Eastern Standard Time')

             * 2. If the birthdate is in the future, (age is a negative) the age should return 0

             * 3. The birthdate should be rounded down as an integer
