Yes, but that shouldn't make a difference. NTP can slow down or speed up
the clock, but it should never make it go backwards. Especially for a
monotonic clock (as the name suggests).

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 ..
