DESCRIPTION

10        Task time query and utility functions provide information about
11        the time resource usage of the current task. These functions provide
12        information about the user time and system time of the current
13        task. And provide utility functions to turn the reported times
14        into miliseconds and create human readable string representations
15        of task time used. The reported times are approximates and should
16        be used for "coarse grained" measurements only. The reported user
17        and system time are only for the current task, not for the process
18        as a whole nor of any time spend by children of the current task.
