It looks like if ntp_adj held a big negative number you might end up with a smaller output . ntp_adj is signed too .. I don't know how ntp_adj is set though .
I thought I remember George Anzinger speculating that ntp could cause the time to backwards , that's why I brought it up. Maybe if he's read he can clue us in ..
