az monitor metrics list: error: Input '2018-04-24 09:14:07' is not valid datetime. Valid example: 2000-12-31T12:59:59Z
This is the output when the start and end times are the same, it seems to believe that the time is invalid, which isn't the case. Also it's showing the time format as 2018-04-24 09:14:07 which is the internal format and isn't the format supplied which is confusing.
