Inbound pass deflection goes OOB - time?

[eyezen]

2nd quarter 1.8 left on the clock, I am new trail opposite administrating a designated spot throw-in under the basket for team B. Inbounds pass goes out towards table and immediately deflected OOB by the defense. Clock still reads 1.8. Team B calls timeout. Team A wants time off. We discuss during timeout. R decides to leave time as is.

5-9-2 If the referee determines that the clock was not started or stopped properly, or if the clock did not run, an official's count or other official information can be used to make a correction.

Intuitively I feel some time has to come off, but can we justify it and if so how much? Obviously there won't be any accurate count.

Thoughts?
