Is there a limit on the number of years that can be set in the date when using UNTIL or EXPIRE keywords?
The only limitation is that it cannot exceed 99 years because the field is only two characters. If you specify a date into the next century it will be honored.
For example:
TSS PERMIT(USER01) DSNAME(HANK.*) UNTIL(07/24/09)
The above permit will expire in 2109 since 2009 has already passed.
