Hi Sam,
Welcome to this Microsoft Project newsgroup
Two possibilities. I guess you mean summaries of phases. A summary's Duration is measured from the Start of its first task to the Finish of its last task, and thus could well span part of a day because of resources availability etc.
Or it could be caused by a miss-match of Calendars and working time. See FAQ Item: 5. Default Working Hours
Finally, if you're using Project Pro and Server, then try posting on the microsoft.public.project.server newsgroup (forum). Please see FAQ Item: 24. Project Newsgroups. FAQs, companion products and other useful Project information can be seen at this web address:

Hope this helps - please let us know how you get on
