R help - Apr 2017 - as.POSIXct character string is not in a standard unambiguous format

Hi

I have lots of issues when I try to install R 3.3.3 during the "make 
check" step.

Every time a call to as.POSIXct is done in test scripts, I got the same 
error message:
e.g. x <- as.POSIXct("2002-02-02 02:02")
Error in as.POSIXlt.character(x, tz, ...) :
   character string is not in a standard unambiguous format


It looks to be linked to localtime but when I compiled R 3.3.2  6 months 
ago, the same test scripts were there and succeeded.


Is there an environmental variable to use to change the as.POSIXct behavior?

Regards

Hi,

I can't answer the question about R 3.3.3, but I don't see anything in
the update notes.

http://mirror.its.dal.ca/cran/doc/manuals/r-release/NEWS.html

In the meantime, would it skirt your issue if you explicitly stated the format?

x <- as.POSIXct("2002-02-02 02:02", format = "%Y-%m-%d
%H:%M")

Hi Ben

Thanks for your answer
I have already tried this, as well as
     x <- as.POSIXct(strptime("2002-02-02 02:02", "%Y-%m-%d
%H:%M"))
It works! But it does not fix it widely for all tests used during the 
"make check" step at compile time. Unless I patch all of them.

There is something with localtime but I cannot find what.

On another machine with another Linux OS, and the same environmental 
variables
    x <- as.POSIXct("2002-02-02 02:02")
works fine.
