Previously:      hardware level
Previously:  A recent discussion with my co-wokers about synchronizing OS time has
Previously:  prompted this question:
Previously:  Does ntpdate and/or rdate affect the date and time at the hardware level
Previously:  or just at the OS level?
Previously:  The man pages do not discuss this.

I received several answers of varying degree.  The general consensus is
that, depending on the OS/motherboard the BIOS (or real time clock) may
adjust itself when ntpdate/rdate is called.

Intels running Linux will not update the RTC; Solaris/Sparcs will.

Thanks to those who answered.
