Session Browser Wait Time (Toad 12)

What is the unit of measurement for the wait times shown in the Toad session browser, on the wait tab?

For example, I see ‘enq: TX - row lock contention’ with a wait time of 690. Does that mean 690 seconds, 690 centiseconds, 690 single-block disk reads, or what?

This must be somewhere in the documentation, but I can’t seem to find it.

Thanks.

To answer my own question: after repeating the search in the documentation, I got the answer. The unit is displayed in the field on the upper right corner of the session browser page. The default appears to be centiseconds and it can be changed.
