Allow a JQL query for a specific time span of the day, from a period of time

Problem Definition

At this moment, it is not possible to query events for a specific time span of the day, from a period of time.
For example: Show me the issues created in the last 6 months that were created between 17h00 and 08h00.
This won't be possible.

Suggested Solution

Allow a JQL query for a specific time span of the day, from a period of time.

Why this is important

It is relevant to managers/admins to understand which time of day is the most intense of issue creation, for example.

Workaround 

If needed, the admin can export the issues to a csv file and use the spread sheet editor (Office, OpenOffice, Numbers, etc) to perform the query.
