Answer:
Since the time zone of the Galapagos Islands is UTC -06: 00, while the time zone of Iceland (including its capital, Reykjavik) is UTC 00:00, the time difference between both territories is 6 hours behind in the Islands Galapagos with respect to Iceland.
Thus, since 12:00 AM implies 00:00 hours or the beginning of the day, if it were 12:00 AM on January 7 in Reykjavik, it would be 06:00 PM on January 6 in the Galapagos Islands.
