tid.
atproto record keys are timestamp identifiers — 13 chars of base32-sortable text packing a 53-bit microsecond timestamp and a 10-bit clock id. live-generate them or paste one to see exactly when it was minted and by which clock.

13 chars · base32-sortable · alphabet "234567abcdefghijklmnopqrstuvwxyz" bit layout (65 bits → 13 × 5): [1 bit] leading zero [53 bits] microseconds since 1970-01-01 utc [10 bits] random clock id (disambiguates rapid inserts) sort order equals time order — new tids always come after older ones, and two tids with the same microsecond diverge by clock id.
