It may be more complicated than that. The years around 1900 looks like a
busy time in the history of the Cook Islands – 15 islands spread over 2.2
million sq km (850,000 sq mi) of ocean, 8.5 degrees of longitude and 13
degrees of latitude – which may not have all been in sync. More than one
time zone might be necessary to correctly reflect the ground truth, though
I recognize it's out of the primary scope of tzdb. If a South Pacific
history buff was interested in a project ... :)
