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]]
