Three dates can tell different stories
A page may be published on one date, describe an activity that began earlier, and remain online for years. Recording observation time answers when the source was seen. A validity period, when known, answers when the fact applies. If the source does not establish an end date, a date should not be invented to close the history.
Time can weaken a present-day conclusion
Capabilities, facilities, leadership, and economic relationships can change. Older evidence may remain useful as history while being insufficient to say something is true today. Comparing two moments also requires compatible subjects, observation conditions, and methods; otherwise an apparent difference may come from how the information was measured.
Do not confuse capture time with event time
The date a system or person accesses a page is an observation about access to that page. It does not by itself establish when the described activity began or ended. A temporal transition needs references that place the event in time, and sometimes the exact date simply is not published. In that case, preserve the unknown interval instead of manufacturing continuity.
Currentness depends on the attribute and context
Information does not all age at the same rate. A registered address, certification, product catalogue, and commercial relationship may require different checks. Review frequency should reflect the chance of change and the decision that depends on the information. A general “recent” label cannot replace this specific explanation or guarantee that the content remains correct.
Conceptual example
Hypothetical example: a 2022 catalogue describes a manufacturing line. If the same page is accessed in 2026, the new visit confirms that the page is available, not that the line still operates. Without additional temporal evidence, current capability should not be presented as confirmed.
Scope and limits
A recent date does not guarantee accuracy, and an old date does not automatically make a historical claim false. “Currentness unknown” is valid when it is unclear whether a state continues. A change in source, language, or instrument may prevent a direct comparison.
