Flow XML Archive Filename
On 0.7.x versions, can anyone tell me how the numeric prefix for flow
backups is generated?
Example: 8548619576826734-flow.xml.gz
I apologize for the "read the code" question, but GitHub won't let me
search anything other than master from the website and I'm not in a
position to pull down the code to grep right now.
I appreciate the assistance.

Got ya. Here is the old way it was done [1].
final Path archiveFile =
archiveDir.resolve(System.nanoTime() + "-" +
configFile.toFile().getName());

Joe,
Thanks for the reply. I did find that code in my search, but it seems to be
the "new" 1.x method of archive file naming. The new method is a lot easier
to eyeball and see that it's concatenating date/time values.
Example: 20170405T164814+0000_flow.xml.gz
Unfortunately, I'm looking for the "old" 0.x file naming... which seems to
be some long integer calculation of time.
Example: 8548619576826734-flow.xml.gz

Nick,
The details for that can be found here [1]. It isn't exactly meant to
be a public interface in terms of the naming being reliable thought so
take care to rely on it programatically.
