R-devel build failing (future file timestamps)


I am having trouble passing R CMD check without warnings because of the following error

* checking for future file timestamps ...Warning in file(con, "r") :
  cannot open URL 'http://worldclockapi.com/api/json/utc/now': HTTP status was '403 Forbidden'
unable to verify current time

Looking at the code in R-devel tools:::.check_packages(), it seems that the future file stamps is enabled when checking as-cran. Is there a way to around this on travis-CI (Until this gets fixed in R-devel)?

I have exactly the same problem. Also, I activate as-cran and it passes the release but not the devel

Can you please provide a patch?
