Actually, Stephen is right and you're wrong. The BIPM defines an SI
minute,
hour, and day in exactly this form. See table 6, page 32, of:

It may seem picky, but nevertheless: the BIPM does not define an
"SI minute" in the SI brochure, nor anywhere else. It defines
the time units minute, hour, and day in terms of SI units,
and allows their use together with SI units.
Thus d, h, min are are well-defined units, but they are not
SI units. Calling them "SI-minutes" etc is misleading, in my
opinion.
