tapset::task_time (3stap)

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