uuid7 - time-sortable UUIDs UUID v7 Implementacion in Clarion
This module implements the version 7 UUIDs, proposed by Peabody and Davis in https://www.ietf.org/id/draft-peabody-dispatch-new-uuid-format-02.html as an extension to RFC4122.
Version 7 has the nice characteristic that the start of a UUID encodes the time with a chronological sort order and potentially ~50ns time resolution, while the end of the UUID includes sufficient random bits to ensure consecutive UUIDs will remain unique.
The first 48-bits are the timeStamp in milliseconds on days since 1970-01-01.
on MAP add : include( 'ULID.INC' ),once
on code call : s = NewUUIDv7()
this generate an UUID version 7 like:
"0191944D-8EC4-7A70-86F5-8AA506DEE33A"
This version on standard i5 Gen 12 generate 1.000.000 of ULID in less than 4.5 secs.
