awslogs not finding logs due to documentation ... I think

Hi.

Attempting to find entries for a date range.

`awslogs streams api.xxxxx_access -s '11/08/2017 00:00' -e '11/08/2017 23:59'`

Returns nothing.

I then tried setting the dates the "right" way around ...

`awslogs streams api.xxxxx_access -s '2017/08/11 00:00' -e '2017/11/08 23:59'`

and I get output.

Ran the `get` variant and I got my logs!!!

Start with the `awslogs streams` and `get` command entry points and compare the documented date format with the examples in this report. Clarify the accepted start and end date formats so the documented command reliably returns the intended date range.
