Keep the source time zone
Record the source time and timezone before conversion. “20:00” without a date and zone is insufficient, especially when a viewer is on the other side of midnight.
Use UTC as a reference
Our calendar displays verified normalized times in UTC and offers a local-time display in supported browsers. A changed display zone does not change the stored event or its identity.
A card can run early or late
Undercard duration, substitutions and broadcast decisions can move a bout. Treat ring-walk estimates as estimates; check the organizer’s final announcement.
Avoid the replay mistake
A video upload date or a highlight title does not necessarily identify an upcoming contest. Old bouts remain historical records and must not be offered as a fresh betting calendar.
