If this is the case, the timeout should be the maximum (or reasonable maximum) time an I2C transaction could take.
How long is that? Is one millisecond good enough?
Probably not. If you place a read request to a slow device it may take tens of milliseconds, or even longer - I have no idea. IIRC we had a box with a LCD display connected over I2C, which didn't ent into production as originally designed because writing the content took over 100 millisec.
Best regards,
