Logseq/Frontmatter/logseq-created-time-year

• logseq-created-time-year:: - links an entity to its creation year, decade, or century

• The value is a link to the matching Logseq/Entity/Time/Year instance, at whatever precision is actually known — a specific year, or its decade or century when only that much is known.
• Distinct from date-created::: that property holds the display-quality date value (day, month, or year, per Logseq/Date) and does not always resolve to a Logseq/Entity/Time/Year page. logseq-created-time-year:: always does, so every entity created in a given year, decade, or century collects there as a backlink regardless of the entity's own type.
• Applies broadly, to any entity whose creation year is known: books, movies, podcast episodes, essays, musical compositions, works of art, and others.
• Set alongside date-created::, not instead of it, when both are known.
