Are you sure you are not confused with sys(3)? I never had a problem with uniqueness of sys(2015), I just did a crude test creating a million records in a cursor, it took 0.786 seconds (1272 records every millisecond) and got zero collision.
CREATE CURSOR c_test (PK I AUTOINC, VALUE C(10))
lnStart = SECONDS()
FOR i = 1 TO 1000000
INSERT INTO c_test (value) VALUES (SYS(2015))
NEXT i
? SECONDS() - lnStart
SELECT value, COUNT(*) cnt GROUP BY 1 ORDER BY 2 DESC FROM c_test HAVING cnt > 1
