    Something like

    select concat(cast(sum(datediff(minute,'0:00:00',CONVERT(time,Overtime_HHMM)))/60.0 as int), ':', cast(sum(datediff(minute,'0:00:00',CONVERT(time,Overtime_HHMM)))%60.0 as int))  as TotalHoursWorked
    from Accounts_DailyAttendance where datename(month,processdate) ='March' and datepart(yyyy,processdate)= '2014'

    You might be able to make it a little more intelligent and add the seconds component as well.
