Use the dated rule rather than last year’s memory
The 2026f release notes state that Cuba remains on UTC−04 through 7 November 2027 rather than falling back on 1 November 2026. A conversion tool using older data can therefore produce a different result from a tool using the new release.
A one-hour disagreement around this change is not, by itself, evidence that a stream is delayed by an hour. Civil time, a programme’s scheduled edition and video-delivery latency are different things. Compare the actual timestamps before adjusting playback settings.
One instant, several regional clocks
The sample shows Havana beside nearby North American and Caribbean locations. The relationship is calculated for the dates shown, rather than presented as a permanent regional offset.
| UTC example | America/Havana | America/New_York | America/Jamaica | America/Puerto_Rico |
|---|---|---|---|---|
| 2026-11-03 20:00:00 UTC | 2026-11-03 16:00 (UTC-04:00) | 2026-11-03 15:00 (UTC-05:00) | 2026-11-03 15:00 (UTC-05:00) | 2026-11-03 16:00 (UTC-04:00) |
| 2027-07-15 20:00:00 UTC | 2027-07-15 16:00 (UTC-04:00) | 2027-07-15 16:00 (UTC-04:00) | 2027-07-15 15:00 (UTC-05:00) | 2027-07-15 16:00 (UTC-04:00) |
Update the clock source before applying a guide shift
If all programme times are displaced on an older device, inspect its local-time configuration and available software update first. A manual correction inside one guide may help that list temporarily while leaving other apps on an outdated clock rule.
If the device’s clock is already correct, compare the guide’s source zone and the edition being displayed. A fixed offset embedded in guide data can remain wrong after the device itself has received current time-zone information.
Treat future conversions as date-specific
The examples use the rules published in IANA 2026f. Future civil-time decisions can alter later dates, so a reminder for a future season deserves a fresh check. The broadcaster’s current schedule still decides the programme start; this calculation only converts the stated instant.
Questions about this guide
Does the table prove a programme is available in Cuba?
No. It is a clock calculation, separate from programme availability or service rights.
Why might two devices disagree by an hour?
They may be using different time-zone data versions or different locations. Compare those before assuming a video playback fault.
