I printed the travel requirements and it said:

A rt-PCR test for the SARS-COV-2 virus obtained from a naso-pharyngeal swab only and performed within 72 hours prior to departure to Sint Maarten (last leg in case of connecting flights) is required for all travelers originating from a country that is categorized as high or moderate risk. Other tests such as antibody tests or antigen tests and tests performed outside of this 72 hours period will not be accepted.

It states 72 hours from Departure, not arrival; has something changed?
