Could it be you chose the wrong time-zone when the account was set up? if so, if you go into �Home� on the Hotmail account and click on �Settings� on the left hand side and then on �my Profile� under the �Your information� heading.
You�ll get a wee summary and below that, there is the option to edit the information. Choose that and then scroll down the next page till you see �Home Location� and in that section you can input the time zone and save the change..
