Event date
The time of the event described.
Publication date
The time the source was released.
Capture date
The time a copy was preserved.
Update date
The time a page was modified; it may not reveal what changed.
Date-field normalization
The following scenario is fictional and is included to demonstrate the method. It is not a factual allegation about BLACKOPS, BLACKOPS DARKNET, BLACKOPS MARKET, BLACKOPS LINK or any real service.
A source page shows a publication date but refers to an event from an earlier month; the archive capture occurred later still.
Store each date with its type, timezone if known, precision and source. Never silently fill a missing day or convert a publication date into an event date.
From observation to a defensible publication
A repeatable sequence makes the reasoning visible. Each stage should leave a record that the next reviewer can inspect.

What this page can—and cannot—establish
For “Four clocks that should never be collapsed.”, the strongest defensible output is a traceable description of the available record: what was observed, how it was sourced, when it was recorded and which interpretation follows from it.
This page cannot establish facts that are absent from its cited material. It does not authenticate a similarly named service, identify an operator, prove current availability or certify the safety or legality of a destination.
A future update should change the conclusion only when new, attributable evidence changes the record. Corrections should identify the earlier wording, the new evidence and the date of revision.
