void start ()
 read current time, all further time measurements will be in relation to this time
 
 Clock ()
 calls start()

 nothing particular
 
void set_offset (Microseconds offs)
 allows to specify an offset, that will furtheron be added to all time measurements
 
Microseconds time () const
 return time elapsed since last call to start() in Microseconds (possibly adding an optional offset)
 
Microseconds wall_time () const
 returns the Microseconds passed on the wall clock sind initialization

Detailed Description

allows measuring time difference to its initialization time in Microseconds

the clock is initiliazed by calling start() (this also happens automatically at construction) and returns, at each call to time(), the time passed since the last call to start() in Microseconds (optionally plus a given offset specified by set_offset() ). The routine elapsed_time() prints the current time difference together with current date and time to an output strean.
