Re: [SPAM] Re: Debian clock multi boot (It was: Burn 100min. (878MB) cd-data with k3b)
Hmmm... When I (for what ever reason) must have a dual booting box
(SomeLinux and SomeWindows) I set the hardware clock to GMT (UMT or
which ever name is correct these days). This keeps the *Linux o/s happy
but confuses the *Windows system. I am the only one who uses the box,
and I don't send email from it, so this is not very likely to cause a
problem outside of my own little world.
There may come a time when this is not the case for me, so Jo, could you
elaborate on your comment, "As per the manual, you should configure
Debian to compensate for the mess Windows makes of the hardware clock."
That is, do you set the hardware clock to satisfy Windows and then set
the timezone to an appropriate offset so Linux reads the correct time?
It would seem to me this would give the wrong timestamp for email etc.
Yes, I am looking for the manual reference, but I don't know what to
look for as I write this.
Thanks, fgd.
