Put time back on the clock?

[RecRef]

What would you do when you can’t put the correct amount of time back on the clock?

One point rec game this weekend with 6/10 of a second left. Clock operator starts the clock when the ball is given to the inbounder. (It was his son’s team and they were the ones down by a point. And yes we went over the situation with him beforehand)

Partner goes to the table to set the clock back to 0.0:6. It can't be done. You can set minutes and seconds but not tenths. Both of use tried to work the time down to 6/10 but could not. In the end we gave-up with 7/10 on the clock.
