"midnight" has no meaning at South Pole station, nor on the ISS, and
very little meaning at McMurdo other than how tired the supply crews
from Christchurch are likely to be.  At those places the hour 00
designates when the calendar day and date change.

The concept of midnight is itself a localization of us temperate zone
folks, and the word "midnight" has no place in tz other than in a
footnote explaining the origin of the simplifications codified in the
underlying tz model of time and date.
