/*! \class PISystemTime
* \brief System time
*
* \section PISystemTime_sec0 Synopsis
* This class provide arithmetic functions for POSIX system time.
* This time represents as seconds and nanosecons in integer formats.
* You can take current system time with function \a currentSystemTime(),
* compare times, sum or subtract two times, convert time to/from
* seconds, milliseconds, microseconds or nanoseconds.
* \section PISystemTime_sec1 Example
