UTC.
I will check this evening. However, one post says Evolution uses System time and not BIOS time. Don't know how to find BIOS time for the phone, but I will google a bit for it

What about the exchange server?  Do you have any access to that to see
what timezone it is set to?
Our Exchange server is 2010 and the timezone for the server is UTC+1 + summertime, which altogether should be summarized to my computers' and my phone's +2 timezone

No, don't include the original - if you reply to a message to the list,
use Ctrl-L (to reply to the list), that will set all the threading
parameters properly so your message will appear in context with all the
others so there is no need to include the original message.  In fact
good list ? email etiquette is to remove any parts of the message that
aren't necessary to the answers you are giving.

P.

Trying to do it right this time... :)

It's unlikely that Evolution (or anything else in user land) will look
at the BIOS time - the standard time is the system time and that is
(very) easily accessed through standard system calls.

P.
Could there be Evolution looking at other time information than phone, OWA and Outlook looks at? (Not sure what I am asking about, but could it be more than one time/date field "living" in Exchange 2010 server, where OWA, Outlook and phone looks at one field while Evolution looks at another)?

I was just going to say that I too see the issues - but having just
looked at my Exchange?EWS calendar (I don't use it very often) and put
some new items in it, everything looks to be OK.  I've certainly seen
things that were and hour off (even "all day" appointments that went
from 1am to 1am), but they seem to have resolved themselves.  I wonder
if an update to Exchange fixed it ('cos I know our Exchange server was
updated recently).

P.

Thank you. Comforting to see that it is not just me.... Our Exchange server is 2010 and the timezone for the server is UTC+1 + summertime, which altogether should be summarized to my computers and my phone's +2 timezone. I will ask the IT management department if there is a possible upgrade up front.
