date and time displayed under Windows has a big difference

[David Rankin]

Paresh:

    I have experienced a time server mismatch that I have never been
able to resolve. With samba acting as a time server and my server
hwclock set to GMT, the time served by Samba appears to apply the
timezone offset in the wrong direction. Here are some of the posts I
have collected and received. I hope some of it is useful to you. If
anyone has some new information on this problem I would be greatful for
a response.

I have posted this problem numerous times -- with no resulution, I am
including to

Brian my problems are slightly different but certainly qualify as "wonky
time."
My problem is with Mandrake 7.2 (stock - installed via ISO image) and
Samba 2.07
(stock - installed via same ISO image) when Samba is acting as a time
server. I
can't set my Hardware clock to GMT and get Samba to serve the correct
time.
Whenever I set my hardware clock to GMT and properly config my timezone
files,
Samba serves time to my Windows machines that is either GMT (with
localtime set
to [no selection]) or GMT + 5 hours (with localtime set to
[America/Chicago]).
The only way I can get Samba to serve the right time is to set my
hardware clock
to CDT (with localtime set to [America/Chicago]).

Now Samba serves the correct time to the WinXX machines, but if I send
mail from
kmail on my Linux box, all of my e-mail is time stamped CDT-5hr. or GMT.
Go
figure? Somewhere an offset is getting applied in the wrong direction. I
still
haven't sorted this out, but I am still working on it as time permits.

I sure wish someone had some additional ideas on this....

Hello Andrew, thanks for the idea. This is really the first logical
sounding
explanation for the timeserver problem I'm dealing with. The localtime
soft link
does effect what Samba sends (I can change it and see that samba serves
different
times). The problem has been that the time Samba sends just makes no
sense. The explanation
that Samba doesn't know the correct offset to begin with really fits
with my
problem. I will dig into the start up and try to find out where the
timezone config is
taking place with respect to where samba is getting started.
