What JQL should I use, so that issue should get auto-assign from 4:00 am CT to 1:00 pm CT. I am using below JQL but issues are not getting auto-assigned from 4 am ct to 1 pm. it gets auto-assigned from 10:30 am ct and continues after 1 pm which should not happen.
created >= startOfDay(4h) and created <= startOfDay(13h)
created >= startOfDay(-1h) AND created <= endOfDay(8h)
GMT(-6) Chicago is the default time
