How Long Was That Event?

Taiob Ali shows that some extended event times are in milliseconds, some are in microseconds, and some are in unknownaseconds:

There was a question in dba.stackexchange.com titled “module_end extended events duration in microseconds?” that I answered and it was Microsecond in that instance.
Later on I questioned myself if the duration is always in Microseconds for extended events. I found, it is a mix of Millisecond, Microsecond and some are unknown meaning famous NULL. I wrote below tsql code to determine which is what.

Click through for the script that Taiob used to determine the answer.
