4.6.4.2.1 RRP Data Parameter: Replay Factor
It is possible to speed up or slow down the replay by a replay factor. However, this feature is only avai-
lable, if reading from file. Reading from standard input is done with the speed that the incoming tele-
grams dictate.
If the replay factor is set to 1, replay is done according to the time determined by the input records.
The delay between the sending of two consecutive telegrams is given by the difference of the time
of day, if available, or by the difference of the time of receipt, found as fourth and third entry in every
raw data record.
The delay is calculated by the replay factor multiplied with the time difference of two consecutive tele-
grams. That means: replay speeds up by the factor 10, if entering the replay factor 0.1, replay slows
down by the factor 10, if entering the replay factor 10.
