Datetime wrong in FIM portal

Hello.

I'm flowing a date "2014-12-31" to the enddate attribute in FIM, iam running it through datetimeformat and when i look at the attribute in database it looks ok, 2014-12-31 00:00:00.

But... when i look at the date in FIM portal it has changed to an earlier occation, IE "2014-12-30 16:00:00" this is causing rules to fail.

How can this be fixed, timezone in Sharepoint seems to be ok.
