Current date/time defaulting is one hour off

Hi - I've noticed that if I default a Date/Time field to the current date +0, it defaults to one hour before now. I have this setting enabled for the My Date/Time field: "Use current date plus 0 days as default value for newly created records" In a record I created just now, I see these values: Created At: 2012-04-30 09:13 My Date/Time: 2012-04-30 08:13 The 9:13a above matches the current time on my local clock. The 8:13a above is one hour before now, in my local time. I have my user timezone in Rollbase set to the same timezone as my local clock.
