| Please note that the internal system clock as used by the Linux kernel | has to be always in UTC as this is the reference for the correct localtime | of the user space. If you are choosing localtime for CMOS clock you may | check the user manual for the side effects.
Adding such a warning is useful. Small changes: | Note: The internal system clock as used by the Linux kernel must | always be in UTC, because this is the reference for the correct localtime | in user space. If you are choosing localtime for CMOS clock, | check the user manual for background information about side effects.
Nevertheless the user has to be informed that the Day Light Saving switch for the CMOS clock has to be done by him self. Even if technical this is required by the system.
Maybe Karl has a few words to make clear that locatime in CMOS clock is a fragile and requires periodic maintenance within the CMOS.
This we probably must add to the manuals. Please, reassign the bug to the docs team, once the text changes are implemented (or clone this bug, etc. pp.). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
