Unfortunately mssql isn't great at custom date formats. You're stuck with string parsing:

e.g.

select replace(CONVERT(varchar(13),date_field,121),' ',':')

The full details of the formats that are available are here: http://msdn.microsoft.com/en-us/library/ms187928.aspx

Note: If you're lucky enough to be in SQL 2012 you get a new FORMAT function, which is basically a wrapper of the .Net equivalent: See here: http://msdn.microsoft.com/en-us/library/hh213505.aspx
