Island Time Mystery Cache

This cache is a relisting of Corikra's 'Island Time' - GC2JV5B.

A great puzzle that that all becomes clear when the penny drops. It surprisingly only had 33 finds, with 4 favourite points between 28/10/11 to 25/05/17

You're on island-time now, so relax, listen to the waves and watch the clouds.
