There are many ways to code searching for this. Here is my solution:
LOCAL ldDate, lnStart, lnStop
lnStart = SECONDS()
ldDate = DATE()
llFound = .F.
DO WHILE NOT llFound
ldDate = ldDate + 1
llFound = NOT HasDuplicates(ldDate)
ENDDO
lnStop = SECONDS()
?ldDate
?lnStop - lnStart
FUNCTION HasDuplicates
LPARAMETERS tdTestDate
LOCAL lcTestDate, llDuplicate
lcTestDate = DTOS(tdTestDate)
llDuplicate = .F.
FOR ii = 0 TO 9
IF LEN(CHRTRAN(lcTestDate, TRANSFORM(ii), ""))<7
llDuplicate = .T.
EXIT
ENDIF
NEXT
RETURN llDuplicate
ENDFUNC
