g++4.5.2 cann't compile (Formatting a Date/Time as a String)

[eric]

Dear Ubuntu programers by g++:

  I copied a piece simple (Formatting a Date/Time as a String) program
from book(c++ cookbook), chapter5 Section2, Example5-4, on page 201.
on my g++4.5.2(ubuntu10.04, with kernel 2.6.35-25)
you can get that example code from
http://examples.oreilly.com/9780596007614/
to test by yourself

I got compile errors
