Compare three clocks
Check the current time on the viewing device, a trusted local clock and the guide’s “now” indicator. Then compare one programme against its current official schedule. Record the date as well as the time: overnight programmes can appear under the previous day in another zone.
If the device clock itself is wrong, repair that first and reopen the guide. An EPG correction applied over a wrong system clock can create a second offset when automatic time later starts working.
Check the feed before changing the offset
A national brand may have regional services or time-shifted versions. Record the full channel label, including region or language where present. A guide matched to another edition can show plausible programme names at consistently wrong times. An offset cannot repair a schedule belonging to a different feed.
If only one channel is affected while nearby listings are correct, retain that mapping as the main clue. If every entry shifts by the same amount, inspect the guide’s time-zone setting and system time before editing individual channels.
Use a reversible correction
- Note the present device time-zone and EPG settings.
- Refresh guide data once using the player’s documented controls.
- Recheck a current and a later programme.
- Apply an offset only if the player supports it and the mismatch is consistent.
- Retain the original value so it can be restored after the feed is corrected.
Recheck after time-rule changes
Canada does not have one national local clock. The NRC directs readers to provincial and territorial authorities for the most accurate current time-zone rules. Do not schedule a recording from “Canada time” or assume a fixed gap between two cities throughout the year.
A correction that helps today may become wrong after a local time-rule or guide-source change. For persistent errors, report the device clock, selected zone, channel edition and two concrete programme examples. This provides evidence for a mapping repair rather than merely another manual offset.
Related questions
Does a one-hour error always mean daylight saving time?
No. It can also mean a different regional feed or incorrect guide-zone setting.
Will refreshing the guide restore missing replay rights?
No. Listing data and replay availability are separate. A correct guide does not grant catch-up access.
