Time of System to BIOS Time
This function block is used to synchronize the BIOS time with the value of the system time.
If the input bSync is HIGH, the BIOS time will be set to the current value of the system time. In this way the hardware clock can be set by an application.
This function block is useful in combination with the real time clock (RTC) function block.
Attention: Be aware that changing the BIOS time to an earlier date is not recommended. It can lead to conflicts with existing files and their time stamps in the file system, because it is now a point of time in the future.
