Measure what each number describes
The film running time describes a particular version of the work. The schedule block describes the period allocated on a channel. Depending on the actual broadcast, that period can also contain breaks, presentation or other material. Read the labels before comparing numbers.
For example, a 100-minute film inside a longer television block does not supply the exact film start and end points by arithmetic alone. Observe the presentation or use explicit official details rather than subtracting an assumed fixed amount.
Confirm the work and version independently
Keep the full title, year and any stated edition. Films can share titles, and different versions can have different lengths. Those identity details are stronger evidence of a version difference than the length of a schedule slot.
A station such as CHCH carries films within a wider schedule. Its block tells you when to plan for the broadcast; it does not automatically document every detail of the underlying film edition. Use the official film or programme information where the version matters.
Plan the evening around the broadcast
If watching live, allow for the actual scheduled block and possible programme transitions. If another appointment follows, do not assume the film will finish after precisely its catalogue runtime from the listed slot start. The presentation can affect that expectation.
If you have a recording or replay feature, check its actual beginning and end before a group viewing. A listing label alone cannot prove the full film was captured. This check is about the result you have, not a claim that every service offers those features.
Keep a report about the right discrepancy
If the wrong film is playing, provide title and year evidence. If the film is correct but the guide’s end time is wrong, describe the actual boundary. If the concern is an unexpected edition, retain the explicit version information.
Avoid treating all three as a clock fault. A global offset cannot change a film edition or repair a truncated recording. Start with the measurement that actually differs and preserve the surrounding schedule so the correction can address the correct problem.
Keep the stated duration with its source: catalogue runtime, scheduled slot or observed playback length. Writing those labels beside the numbers prevents a later comparison from mixing three different measurements and turning a straightforward presentation difference into an invented fault.

Does a longer slot prove an extended cut?
No. Confirm the film version separately.
Can I calculate exact break time from two runtimes?
Not reliably without knowing what each measurement includes and observing the actual presentation.
