Programme-guide time depends on the chosen time zone and date
A programme guide should make its time-zone basis clear rather than treating all European locations as one clock.
IANA's time-zone database tracks offsets and daylight-saving rules by location and date. For a mismatch, record the guide's stated zone, the device's zone and the date of the event. An EPG listing alone does not prove the associated source is available or currently playable.
A practical check
- Identify the guide's stated time zone
- Check device zone and date
- Compare the same dated event

A one-hour guide difference needs a dated time-zone check
A guide that appears one hour early or late may involve a time-zone or daylight-saving mismatch, but the symptom alone does not prove it.
Compare the same event and date against a source stating its zone. Avoid a permanent manual offset before establishing whether the device, app or guide already applies seasonal rules. Keep a reversible record of any change.
A practical check
- Record date and location
- Check device and guide zones
- Compare one event before changing offsets
Events near midnight can fall on a different local calendar date
Converting a scheduled time can also change the date for a viewer in another time zone.
Record both the event's original dated time and the intended display zone. A bare clock time is insufficient for an international schedule. Keep the day label visible on fixtures and programme entries so a correct conversion does not look like a missing event.
A practical check
- Keep the original dated time
- Use a named display zone
- Show the resulting date as well as time
A guide and source must refer to the same channel edition
A shared channel name does not establish that two regional editions carry the same programme at the same time.
Record the actual source label and guide entry rather than silently substituting another edition. The website should not invent a local catalogue or programme entitlement from a channel logo. A guide mismatch requires checking the specific edition and dated schedule.
A practical check
- Record the full source label
- Record the dated guide entry
- Compare the intended edition
A past guide entry is not a replay entitlement
An EPG can show historical programme information without providing a playable recording.
Keep schedule display, catch-up availability, recording and on-demand access separate. Check what the legitimate source and actual account offer for the named programme. Do not describe a past date in a guide as a promised replay window.
A practical check
- Identify the past programme
- Check the actual replay control and terms
- Avoid inferred retention periods

Questions answered
Should every European viewer see the same local clock time for a programme?
No. Local times depend on location, date and the guide's stated basis.
Does a programme appearing in an EPG prove it can be watched?
No. A listing and actual playable access are separate matters.
Should I permanently shift every guide by one hour after one mismatch?
No. First identify the zone, date and whether seasonal rules already apply.
Can the correct UTC offset for a location change with the date?
Yes. Applicable daylight-saving rules can change the offset.
Why does a late-night programme appear under another day in my location?
A time-zone conversion can cross midnight and change the local date.
Is a time without a date enough to compare an international schedule?
No. The original date and applicable time zone are needed.
