Protocol 0.2

Temporal Assertion Protocol

Every time-bearing claim is typed.

Temporal types

·EXACT-STATED (clock time quoted, clock identified)
·APPROX-STATED (source’s hedge preserved verbatim)
·RANGE-STATED
·DOC-HEADER (binds the document, never the events narrated in it)
·EVENT-STATED
·MEDIA-RELATIVE (offset into a recording; clock conversion requires a stated activation-time assumption, printed)
·DEVICE-CLOCK (timezone/accuracy unverified until reconciled)
·SECTION-SCOPED
·ORDINAL (before/after only)
·UNPLACEABLE (goes to an unordered annex, never interleaved)
·CONFLICT (both values printed)

·(a) for each entry, state in one line exactly what temporal proposition the source supports;
·(b) maintain a clock ledger (CAD, each BWC unit, dashcam, phone extraction with declared timezone, jail phone system, lab LIMS) with any cross-calibration events; intervals may be computed only between same-clock times or clocks with a stated offset;
·(c) any derived time is tagged INFERRED-TEMPORAL with the derivation shown;
·(d) a report’s header/incident time is never inherited by facts narrated inside the report;
·(e) approximate times are never promoted to exact for arithmetic.
