Just an observation that may well be very stupid. Since Linux/390 can use NTP to sync time, then it must be that Linux/390 uses a "software" clock instead of the hardware clock (TOD clock). Is this true? If so, what happens if somebody down the line in the kernel maintainers decide that Linux should use the TOD clock instead of a "software" clock? Wouldn't that cause a problem? Or am I worrying about nothing. Unfortunately, I don't have the Linux/390 kernel source around, or I would look myself. I do know where to browse it on the Web, but only if I know the module that I want to view. I can't use grep to find where the clock lives.
