OK, with sending client now and date through Service to DB is like:
Date is OK regardless server date - so the client date goes to DB
Date and time - here date is OK regardless server date, time is client time +7 hours...On the client there was 7:33 in DB 14:33 appeared - which is not what we want :).
If we'd like to know when in server time user made an operation, we can simply use today or now on the server side, so the client side now and today never should change.
For best results, use the Firefox browser..
