A DESCRIPTION OF THE PROBLEM :
The documentation rightly says:

> Gets the previous transition before the specified instant.

But then it incorrectly says:

> This returns details of the previous transition **after** the specified instant

and

> Returns: the previous transition **after** the specified instant



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expect it to say

> This returns details of the previous transition before the specified instant

and

> Returns: the previous transition before the specified instant
ACTUAL -
> This returns details of the previous transition **after** the specified instant

and

> Returns: the previous transition **after** the specified instant
