    Before you start stuffing the string, make sure that times before 10 AM are stored with leading zeroes. If not, you might have a problem when 9:00 AM tries to turn into the hour 90.

    Hmm, good point.

    How about this?

    select convert(char(8),

    convert(datetime,

    convert(datetime, stuff(stuff(right('0' + '154040',6),3,0,':'),6,0,':')) -

    convert(datetime, stuff(stuff(right('0' + '133737',6),3,0,':'),6,0,':'))),

    108)
