Time Zone Problem

I previously had Lotus Notes 4.5 on my computer at work and was able
to have Notes' Time Zone Set to Central Time and my Operating System
set to Mountain time. I need it this way as I work on a Team that is
located in Central ( I am in Mountain time) and I need to see all the
forms in the databases with the same dates and times as seen by my
team members. All worked ok. Now I have been upgraded to Notes 6.5 and
it seems that the operating system time zone and notes are tied
togetrher and I cannot separate them. I tried going to the bottom
right of Notes and clicking on I believe it's called Office and then t
on Admin. I change the Time zone to central time and I see the dates
and times correctly (same as my counter parts in Central) on the
LotusNotes Data Base forms however my system clock changes also.
When I get invited to a meeting and Accept it in Outlook it puts it in
my calendar at the wrong time because it thinks I am in Central time.
If I change the time in the Op system then Lotus changes time also.
Any work arounds for this?
