Page 33 in the PD11 UG indicates that the timeline ruler is in minutes, seconds, frames for PD11. The user in the above post claimed that his timeline ruler can indicates 1/100 of a second not frames.
I see no difference in the way it is documented in PD14 or earlier versions of PD. It would be interesting if anyone else can move audio 1/100 sec. instead of 1/10 of a frame in another version of PD.
