Er... in Linux the system clock always uses UTC time, regardless of what the users' settings are. It is the CMOS clock that can use UTC or Local Time, for the use of that other OS when you double boot.
With this definition I'm at a loss what you mean by system clock then.
The internal kernel timer counts the number of seconds since January 1 1970
There is only one system clock that keeps time in a human format, and that is the CMOS clock
The kernel timer is the system clock, ie, the operating system clock (I consider the kernel part of the OS). I should probably have used that full name to avoid confusion. Another name is software clock, although it is based on a programmable timer chip that interrupts periodically the cpu - thus hardware - and then the software counts the interrupts - thus software -. But the cmos clock, or bios clock, or battery backed clock, can probably be called hardware clock as it runs without help from the computer or its software. As it is "stand alone", it is not a "system" clock, or rather "OS clock". Is that clearer now? :-) - -- Cheers, Carlos E.
