[R-pkg-devel] Failed: Future File Timestamp Check

[Simon Urbanek]

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
