\doxysubsection{Detailed Description}
Timer allowing to measure time between a start point and a stop point. 

This timer allows the user to measure user time, system time and wallclock time between two points. Basically, user time is time spent in developer code ; system time is time spent during the IO wait and system calls ; wallclock is the difference of time we could observe by measuring time with a watch.

Measures the system time spent since the last \mbox{\hyperlink{classeo_timer_a571a4faede8822dd1e5e927e6e2f5155}{restart()}}. 

If the number of elapsed seconds is zero, the spent milliseconds are added to a remainder. If the remainder exceeds one second, it is added to the number of elapsed seconds.

\begin{DoxyReturn}{Returns}
Number of seconds elapsed in system (kernel) space.
