| class | TimerGroup |
This class is used to track the amount of time spent between invocations of its startTimer()/stopTimer() methods.
Given appropriate OS support it can also keep track of the RSS of the program at various points. By default, the Timer will print the amount of time it has captured to standard error when the last timer is destroyed, otherwise it is printed when its TimerGroup is destroyed. Timers do not print their information if they are never started.

| void Timer::startTimer | ( | ) |
Start the timer running.
Time between calls to startTimer/stopTimer is counted by the Timer class. Note that these calls must be correctly paired.
