I haven't been able to make this code work. What does it do compared to:

\documentclass[11pt]{book}
			\usepackage{calc}
			\newcounter{hours}\newcounter{minutes}
			\newcommand{\printtime}%
			{%begin definition
				\setcounter{hours}{\time/60}%
				\setcounter{minutes}{\time-\value{hours}*60}%
				\thehours:\theminutes%
			}%end definition
\begin{document}
	This file was saved as \jobname \hspace{1mm} on \today \hspace{1mm}  
at \printtime.
\end{document}
