Josiah,
that test tests the accuracy of the system clock by querying
https://worldtimeapi.org/api/timezone/etc/UTC so my guess would be that you
have either network or proxy issues which cause that request to fail by
providing garbage instead of the actual response.
The call to test yourself is
> readLines("http://worldtimeapi.org/api/timezone/etc/UTC";, warn=FALSE)
[1]
"{\"utc_offset\":\"+00:00\",\"timezone\":\"Etc/UTC\",\"day_of_week\":3,\"day_of_year\":36,\"datetime\":\"2025-02-05T01:42:19.272728+00:00\",\"utc_datetime\":\"2025-02-05T01:42:19.272728+00:00\",\"unixtime\":1738719739,\"raw_offset\":0,\"week_number\":6,\"dst\":false,\"abbreviation\":\"UTC\",\"dst_offset\":0,\"dst_from\":null,\"dst_until\":null,\"client_ip\":\"121.98.39.155\"}"
It has to have the "datetime" entry. If you can't fix your network you can skip
that test with
_R_CHECK_FUTURE_FILE_TIMESTAMPS_=FALSE
Cheers,
Simon
