Setting correct Day/Time

[DarkHelmet]

I used the 'Set Clock' icon in V2 Video Manager to supposedly set the clock in the camera and after much fussing I did get a 'Success' message but the video data still shows a date from 4 years ago- any idea how to get this error corrected? The file names do have the correct date/time showing but the actual video and metadata for the video are wrong.
