[R-pkg-devel] Checking for future file timestamps - warning with worldclockapi HTTP status 403 Site Disabled

As of ~7 hours ago, the warning is suppressed:

https://github.com/wch/r-source/commit/31ee14c620eb1b939acd322f3b5617f998aab8e8

(But the service still doesn't work)

It appears that the code was added by BDR on 2 Sep 2018:

I assume we are seeing failing R CMD check results because
http://worldclockapi.com/api/json/utc/now has recently died.

It would be appreciated if someone from R-core could look into this as
it's currently causing all R-devel builds on travis to fail.

The timestamp checking code is still present in R-devel. I presume

something needs to be done about the breakage.

I think perhaps "stealth fixed" may be more appropro since it's not

in SVN logs, Bugzilla nor noted prominently in any of the various NEWS*
files.

Then there's the "why was the core R installation using a third

party, non-HTTPS site for this to begin with".

And, in other news, there are tests in the R source that rely on a

check of `foo.bar` for connectivity. `.bar` is a valid domain and `foo.bar`
is registered. Thankfully there's no current IP address associated with it.
Anything under `*.invalid` (https://en.wikipedia.org/wiki/.invalid) might
be a better choice as well since that won't break the reason for the
connectivity checks and won't arbitrarily send telemetry pings to third
parties in the even anyone outside of R Core decides to run the tests (say,
when patching something in R).

I can confirm the same when checking on travis with r-devel.

And thanks for the tip with

env:
- _R_CHECK_SYSTEM_CLOCK_=0

In .travis.yml

Seems to be working now

Dear All,

Checking a new package under development produces a warning in a

local R-devel MS Windows environment (output below).

Building it with R-devel on Travis fails (because warnings are

changed to errors), but is successful when setting environment variable
_R_CHECK_SYSTEM_CLOCK_ to zero.

No issue occurs when checking and building with R-stable and

R-oldrel on Travis, or with any R version on win-builder.r-project.org.

The warning concerns using http://worldclockapi.com/, which

however seems out of service ("The web app you have attempted to reach is
currently stopped and does not accept any requests."). This is referenced
in the main function for R CMD check (
https://svn.r-project.org/R/trunk/src/library/tools/R/check.R) and may
concern more R-devel than R-package-devel. I am posting here to check if
the issue was noticed by other package developers and to check the impact.

Thanks for any suggestions.
Best regards,
Ralf
