"32 time zones"

[Arthur David Olson]

	Our society has created a fictional time system of 32 time zones
	(24 one-hour offsets and several more half-hour and three-quarter
	hour offsets).

A grep in /usr/lib/zoneinfo/* on a SunOS 4.1.1 system failed to show up eight
oddball time zones (see attached).  Does anyone know of the origin for the
"32" time zones?
