I suspect you have cygwin\bin in your PATH variable,
as that does not look like Windows date command:
> system("cmd.exe /c date /T")
Wed 03/07/2012
> shell("date /T")
Wed 03/07/2012
> shell("date") # asks for new date if no /T
The current date is: Wed 03/07/2012
Enter the new date: (mm-dd-yy) Warning messages:
1: running command 'C:\Windows\system32\cmd.exe /c date' had status 1
2: In shell("date") : 'date' execution failed with error code 1
sessionInfo() does not report PATH's contents. You can
look at it with
strsplit(Sys.getenv("PATH"), .Platform$path.sep)[[1]]
