[tz] Ethiopia local time

>               int tm_hour;    /* hours since midnight — [0 23] */

> This means that tm_hour has to be 0 at midnight

I think this means that the hour has to be 0 when the calendar date changes.

The meaning is the number of hours since the change of the calendar
date, and in the usage prescribed by the 1884 International Meridian
Conference that has been midnight.  If the Ethiopian common use of
time and date has the calendar change at sunrise or sunset then the
POSIX requirements are satisfied.
