* \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 PISystemTime::current(),
|
||||
* compare times, sum or subtract two times, convert time to/from
|
||||
* seconds, milliseconds, microseconds or nanoseconds.
