"Businessmen" can keep whatever time they like for internal use, but
whenever a businessman communicates with a customer or another business, the
courts will interpret any times stated as being the legal time of the
applicable jurisdiction, although in many cases the businessman and the
other parties have the option of agreeing to a different time scale. So the
businessman who uses TAI internally must either take great care to convert
this to the appropriate legal time scale when communicating to outsiders, or
must form a contract with each and every external contact to use TAI instead
of the legal time scale that would normally apply.
