Hi, i am one of those who sent Albretch Mueller here after pointing out the conflict between MS-Windows and Linux about local time versus UTC when reading and writing the hardware clock.

(I once had it with Open Solaris and Debian.) I am not sure how to simulate it with Linux-only. Maybe by manipulating the hardware clock from the BIOS, then booting Live, correcting the system time, and shutting down. Then one would look in the BIOS whether the time took a leap. Maybe it happens automatically at start or end of the kernel or maybe it has something to do with the network environment. Like in https://www.kernel.org/doc/html/latest/admin-guide/rtc.html "if the kernel time is synchronized with an external source, the kernel will write the time back to the CMOS clock every 11 minutes." Have a nice day :) Thomas
