Describe "wrong time". Is it wrong after boot by a fixed amount, and
after correction it stays good till next boot? How much is it wrong?
Or does it run fast, or slow, and by what amount?

Please give details.

Particularly, is it off by the difference between your local time and
GMT?  If so, you made a configuration error when you chose your hardware
clock error.


I did not have internet connecting in my opensuse, so it should not be
able to know the GMT.
11.1 would process about 12  hours or less after each time I booted
into it. and it would change the BIOS time.
I think the post here got the same problem:

When you install Linux, you're given the choice of setting your hardware
clock to UTC or local time.  Windows requires local time.  If you select
UTC, but actually use local time, your clock will be off by the
difference from UTC.  You do not require an internet connection to have
this error.  If you choose GMT Linux will add an offset to the hardware
clock time to display local time.  If you chose GMT and the hardware is
local time, that offset will cause your clock to be off by the
difference between GMT & local time.

Yup, telling Linux to use UTC and dual booting with Windows would
cause this, either uncheck the UTC option in "yast timezone" or keep
UTC and drop Windows :p


BTW, GMT used to refer to the "official" clock, but that use has been
replaced by UTC.  GMT is very slightly off from UTC and it's best to
simply consider GMT as a time zone, for the purposes of offset calculation.
