Strange Desktop background problem

Hi all

OK,i am using my Desktop background to come on every 3 hours(9am,noon,3 pm,6pm,etc).All was OK that is until the clocks went forward.The normal time is fine,but when i try to save the Desktop background's to come on at 3 hour intervals(yes i do save at noon,3pm,6,pm)the Desktop background ALWAYS change 1 hour later then they should.Am i missing something obvious?.Thanks for looking.

Hi A Guy

Yes the windows time is correct,it corrected itself for the daylight savings time.And the Automatically adjust clock for Daylight Savings Time is checked.Thanks.
