BIOS-Time to System
This function block can be used to synchronize the system time with the BIOS time.
If the input bSync is HIGH, the system time will be set to the value of the current BIOS time.
This can be used to keep the system time to a more precise value, if the system time is regularly set to the value of the hardware clock.
This function block is useful in combination with the real time clock (RTC) function block.
