1839

About this time

A period is the time a checked historical passage describes, kept at the precision the evidence gives: a century (only when the passage states one), a year, a month or a day; when a passage states no time, its publication date is used as the latest time it can describe. A smell is linked to it only through a VERIFIED claim on a historical source. Each link records what one source wrote, which may be later than the time it describes; it does not describe a whole city or era, it says nothing about the smell today, and it is not evidence that a smell has changed or disappeared. Decades and centuries only group these records for browsing.
