Detailed Description
Adjust the Time to Synchronize the System Clock.
Function Documentation
◆ adjtime()
| int adjtime | ( | const struct timeval * | delta, |
| struct timeval * | olddelta | ||
| ) |
This method was initially added as part of porting NTP to RTEMS.
It is a BSD compatability function and now is available on GNU/Linux.
At one point there was a static variable named adjustment used by this implementation. I don't see any reason for it to be here based upon the GNU/Linux documentation.
