The SMB connector on the F9T-RCB needs to be dimensioned. X, Y, and Z of the center (signal) pin should be shown.

Using the RCB-F9T ".stp" file, one can measure relative positions of features on the board.

Relative to the right and bottom edges, the SMB housing (square) is centered at ( 61.38 mm, 19.80 mm ). The center of the cable connector pin is 5.44 mm above the top of the board.

Note that these should be dimensioned from a well-controlled location on the card. The card edges are not.

Any of the mounting holes would work, but the center of J1 may be preferred. This will ease definition of an RCB-F9T footprint for Timecard board design, since J1 mates with a header on the Timecard.
