Additional Information

• Set Time sets the current system date and time and starts the system real-time clock. The date and time are passed in a time packet as follows:

Relative Address
Value

0
year

1
month

2
day

3
hours

4
minutes

5
seconds

Then, the call makes a link system call to find the clock. If the link is successful, NitrOS-9 calls the clock initialization. The clock initialization:

1. Sets up hardware dependent functions
2. Sets up the F$Time system call via F$SSVc
