I am building a view for showing upcoming events.

I have my own content type with CCK field with format Date (Unix timestamp) and widget as Pop-up calendar. All works fine, but i views i don't know how to filter it out. I have shown the filter criteria in a screeshot and i don't know what to give in the value field.
