Allow for timestamp version numbers including microseconds

[berlin-ab]

I received this error after adding microseconds to my timestamp:

panic: version number was not valid: Expected component '20190310162427027000' from version segment '20190310162427027000' to be a parseable integer: strconv.Atoi: parsing "20190310162427027000": value out of range

using this Python snippet to generate the version for my timestamp:

datetime.datetime.now().strftime("%Y%m%d%H%M%S%f")

Hey, @Sophichia and I are running into this:

stderr:
panic: version number was not valid: Expected component '' from version segment '.0' to be either an integer or a formatted string

Did you happen to find a fix for your issue?
