adjtimex – Display/Set the kernel time variables.

Summary:

This program gives you raw access to the kernel time variables, like clock tick, frequency, offset, PPL Time constant, etc.

Examples:

$ adjtimex -p — Print current kernel time values.

# adjtimex -w — Provide time details and ask the user to approximate the accuracy.

# adjtimex -c — Periodically (10Sec) compare the system clock with the CMOS clock values and give suggestions.

# adjtimex -t 100001 — Set the no of mSec that should be added to the system time for each kernel tick interrupt.

# adjtimex -f -408033 — Set the system clock frequency offset.
