Has there ever been an attack/leak based on time metadata in UUIDs/ULIDs/Snowflakes/etc (not sequential), in a domain outside of sensitive ones (HIPAA/healthcare, defense)? I'm skeptical that for the vast majority of uses, have time data in the IDs (and also not leaking it from actual timestamp fields) is an issue, and for the cases where it does, just use random IDs. Even theoretically, is there a way to translate timestamps into a German tank problem? If I give you a sampled set of timestamps (with no other node identifiers), can you estimate the cardinality of the greater dataset?
