Historical data - change the time zone

Hello Folks,

I currently use Alpari UK as a broker. I like that their time is GMT+1, because I don't have a Sunday bar on my charts...

I do also some experimenting with historical data which happens to be GMT (so there is a Sunday bar on the chart - which I do not really like).
I know about the period converter and wonder if there is another helpful tool which will help me change the time zone on historical data.
It's basically just saved hour+1hour.

Any input anybody?

Thanks.

maybe I should add that I'm using MT4
