Flight Time Change

Hi all,
I suspect I know the answer to this, but just wanted to check with people that know. I have booked a miles + money flight. The outward sector flight arrival time has changed later by an hour. Given this, is it possible to request from VS a change to my booking for an earlier flight on the same day? - or am I just stuck with it? Its no hardship for me - just out of interest really...
Thanks,
Steve
