An overseas birth record normally shows local clock time. Before entering it into Zi Wei Dou Shu software, record the city, date, historical time zone, and whether daylight saving applied. Check whether the tool converts automatically. Near a two-hour boundary, keep both chart settings for review. A different transformation display may reflect a school setting rather than a different birth time.
Keep the birth certificate's local clock time and birthplace before converting anything. Check daylight saving rules for the exact date and the software's input convention. Compare chart settings one at a time if two results differ.
