At this occasion, we should also correct the switch to
UT - 10:30 h in 1901. That this is wrong is hardly surprising:
on an island without observatory and without telegraphy lines only

that island. "

online at [http://www.paclii.org/ck/legis/ck-nz_act/ciaa1952212/]:

be determined as if that island were situated on the
