Time.h compiling error

i've found few instances of on forums searching, none same i'm seeing.

i won't post code because i'm trying output time sample sketch comes library.  time library folder in library folder, belongs, tried copying .cpp , .h files root of the library folder suggested in thread, no avail.  sketch #include <time.h> throws errors when compile.  here errors:

as errors "variable needs const" tried changing char lines in .cpp file const.  didn't work.  i'm hoping easy, , i'm missing because it's 11pm , i've had few bourbons.  in advance.

/yes, laptop's name lappy.
