Dear all,

As of the current R alpha release, I'm seeing timezone-related warnings on
installing any package (including the recommended ones), which I haven't
seen before. For example,

[~/Documents/Source/R-alpha]$ bin/R CMD INSTALL ~/git/tractor/lib/reportr
* installing to library '/Users/jon/Documents/Source/R-alpha/library'
* installing *source* package 'reportr' ...
Warning in as.POSIXlt.POSIXct(x, tz) : unknown timezone 'Europe/London'
Warning in as.POSIXlt.POSIXct(x, tz) : unknown timezone 'GMT'
Warning in as.POSIXlt.POSIXct(x, tz) :
  unknown timezone 'America/New_York'
Warning in as.POSIXlt.POSIXct(x, tz) : unknown timezone 'GMT'
Warning in as.POSIXlt.POSIXct(x, tz) :
  unknown timezone 'America/New_York'
** R
** preparing package for lazy loading
** help
*** installing help indices
** building package indices
** testing if installed package can be loaded
* DONE (reportr)

This is R-alpha r65266, built from source on OS X 10.9.2 using gcc 4.8.2. I
ran configure with

./configure --with-blas="-framework Accelerate" --with-lapack
--with-system-zlib --enable-memory-profiling
--with-tcl-config=/System/Library/Frameworks/Tcl.framework/tclConfig.sh
--with-tk-config=/System/Library/Frameworks/Tk.framework/tkConfig.sh
CC=gcc-4.8 CXX=g++-4.8 OBJC=clang F77=gfortran-4.8 FC=gfortran-4.8
CPPFLAGS="-D__ACCELERATE__" CFLAGS="-mtune=native -g -O2"
CXXFLAGS="-mtune=native -g -O2" FFLAGS="-mtune=native -g
-O2"
FCFLAGS="-mtune=native -g -O2"

Session info is

R version 3.1.0 alpha (2014-03-23 r65266)
Platform: x86_64-apple-darwin13.1.0 (64-bit)

locale:
[1] en_GB.UTF-8/en_GB.UTF-8/en_GB.UTF-8/C/en_GB.UTF-8/en_GB.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

I see some related material in the NEWS, but no indication that these
warnings are expected. I hope this report is helpful.

All the best,
Jon
