What fortran compiler are you using? Looking into the gfortran library
files I see that date_and_time function is available starting
at gfortran version 4.3.x.

Usually when one gets undefined symbol error messages then one needs
to find out in which library the symbol is defined (using the nm 
program, for instance) and then use
this library when building extension library. For example,
if a symbol foo is defined in /path/to/libbar.a then use
the following f2py command line:
   f2py -c .. -L/path/to -lbar.
