A soft time synchronisation pulse

[Valerik K.]

Please, help to translate.

Phrase is used in the following sentence:

The system will provide a master clock for all subsystems to synchronise their time... A soft time synchronisation pulse can also be provided serially to the controller but is considered as a lower accuracy method for time synchronisation.
Меня интересует смысл "soft time synchronisation pulse".

Буду очень признателен!

ИМХО: импульс синхронизации (получаемый, идущий)от программного обеспечения
