iCalendar invites showing incorrect time in Outlook 2010

Hello,

In the last few weeks, iCalendar invitations sent from Apple's iCloud to my Microsoft Outlook 2010 show the invitation as occurring 1 hour earlier. The body of the invitation that appears in Outlook shows the correct time but the attached ".ics" file, when opened, shows the meeting time as 1 hour earlier. This problem has only started occurring in last few weeks.

Any ideas?

Thanks,

Ben
