Original time evidence
Indices are zero-based. “Previous” means the nearest earlier comparable point in the same segment; unresolved points are skipped, never repaired.
| Track | Segment | Point | Time count | Decoded time text(s) | Time state | Previous point | Skipped points | Relation |
|---|
What this report cannot tell you
- Monotonic timestamps do not prove the correct date, clock or timezone.
- Equal timestamps do not prove duplicate points. Missing optional time alone does not make GPX invalid.
- Only direct GPX 1.1 track-point times are inspected. Route and waypoint times are excluded.
- XML text is decoded and line endings normalized; this is not exact lexical source-byte preservation.
- No full GPX/XSD validation, map, coordinates, track names, repair, sorting or inferred timestamps.
- DTD/entity declarations and XInclude are unsupported. Mozilla/XHTML parsererror names are reserved diagnostics, even if intentionally supplied.
