Why a subtitle file from another edit may not fit one fixed delay
If two editions contain different cuts, a single time shift can align one passage while leaving later passages wrong. Compare more than one recognisable cue.

WebVTT permits different cues to overlap. Distinguish legal timing overlap from an unintended or unreadable presentation in the actual player.
Why subtitle cue 17 does not mean seventeen seconds into the video
A SubRip cue’s sequence number and its start/end timestamps are separate fields. Use the timestamps to locate the displayed text.

Convert the complete date, clock time and offset together. Correct arithmetic can change the calendar day as well as the displayed hour.
