Documentation without examples is just code

This sort of thing is annoying:

https://www.percona.com/doc/percona-toolkit/2.2/pt-query-digest.html

--since
type: string

Parse only queries newer than this value (parse queries since this date).

This option allows you to ignore queries older than a certain value and parse only those queries which are more recent than the value. The value can be several types:

* Simple time value N with optional suffix: N[shmd], where
  s=seconds, h=hours, m=minutes, d=days (default s if no suffix
  given); this is like saying "since N[shmd] ago"
* Full date with optional hours:minutes:seconds:
  YYYY-MM-DD [HH:MM:SS]
* Short, MySQL-style date:
  YYMMDD [HH:MM:SS]
* Any time expression evaluated by MySQL:
  CURRENT_DATE - INTERVAL 7 DAY

I would assume from this document that I could use any of the date stamps so..

20160930 [06:51:05]

a la:
--since 20160930 [06:51:05]

but nope.. explodes can't parse out the thing

--since '20160930 [06:51:05]'

at least realizes it's a time, but also explodes.

--since '20160930 06:51:05'

explodes with THIS:

Argument "20160930 06:51:05 00:00:00" isn't numeric in numeric ge (>=)

Even more funny. SO FINALLY:

--since '2016-09-30 06:51:05'

works (success)

So... WHY NOT JUST ASK FOR THAT. Seriously. Why does the manual page NOT HAVE that exact string in it. What point does it serve to NOT copy in the exact syntax in the block.
