The meaning 'Z' had before ISO8601, and which ISO8601 codified, was "UTC".

If you look at the Canadian time-station CHU's QSL card:

You will notice that the timezones have letters on the illustration
on the wall.  It is not clear to me if the zero meridian have 'N' or
'Z' as designator.

The painting is supposed to despict a meeting in 1879 where Sandford
Flemming first laid out his idea for timezones.
