Applies to: A programme timestamp converts across local midnight in either direction.
The useful distinctions
- A conversion can cross midnight.
- The local date is part of the converted timestamp.
- Searching the original date alone can miss a correctly dated local entry.
Convert the calendar day with the hour
When an event moves past local midnight, the converted hour belongs to a different local date. Recording only “03:00” loses information needed to find the programme in a date-based guide. Preserve the complete source timestamp and the complete local result together. The original announcement is not wrong merely because its date differs from the viewer’s local listing; the two records can still identify the same instant.
Check the neighbouring day before claiming absence
Use the actual converted date to inspect the intended service and programme. Keep the event identity and edition constant while changing the date being searched. If the programme still cannot be found, report the conversion and the inspected window rather than assuming a timezone correction will create a listing. This separates a correct next-day interpretation from a genuinely missing programme record or an unverified availability claim.
Hypothetical worked example
A fictional event is announced for 22:00 UTC on 8 November 2026. A date-aware Asia/Karachi conversion gives 03:00 on 9 November. Searching only the 8 November local guide would overlook the appropriate date window even if the record were present. The example establishes which local day to inspect; it does not claim that any real event is carried by StarShare or that a particular player supplies a future listing.
A previous-date comparison · hypothetical
The checked IANA calculation converts 01:00 UTC on 8 November 2026 to 17:00 on 7 November in America/Los_Angeles. A fictional event at that instant belongs to the 7 November local evening, not the 8 November local page. The viewer uses both the hour and earlier date when searching. The example concerns one instant’s representation, not a permanent offset rule or a promise that a programme record exists.
A focused way to proceed
- Keep the source’s full dated timestamp.
- Convert the date and time together for the viewing location.
- Search the resulting local day instead of retaining the source date by habit.
When to stop or ask for help
Inspect the converted local date and report that complete result if the programme remains missing.
