Custom SQL Reports

Question

I am confused by the use of dates in my SQL. I am getting different totals and can't quite understand why or which syntax is correct. Please see below. Why am I getting 286 and 300?
Query #1 yields 286 tickets.SELECT Count(tickets.created_at) AS "Total Tickets" FROM ticketsWHERE tickets.created_at between '2015-06-01' and '2015-06-30'ORDER BY "Total Tickets" DESCQuery #2 yields 300 tickets.SELECT Count(tickets.created_at) AS "Total Tickets" FROM ticketsWHERE tickets.created_at between '2015-06-01 00:00:00.000' and '2015-06-30 23:59:59.999'ORDER BY "Total Tickets" DESCQuery #3 yields 286 tickets.SELECT Count(tickets.created_at) AS "Total Tickets" FROM ticketsWHERE tickets.created_at between datetime('now','start of month', '-1 month') and datetime('now','start of month','-1 day')ORDER BY "Total Tickets" DESC

I found a trick.
Login as sys on the Grid Repository and execute the following:
insert into sysman.mgmt_ip_report_elem_def values('target_user_table_from_sql','database_target_type',
'target_user_table_from_sql',
'oracle.sysman.db.util.reports.TableTargetRenderController',0,NULL,'EM',NULL,
'10.2.0.1.0');
Insert into SYSMAN.MGMT_IP_ELEM_PARAM_CLASSES
(ELEMENT_NAME_NLSID, ELEMENT_TYPE_NLSID, ELEMENT_PARAM_CLASS, DISPLAY_ORDER)
Values ('target_user_table_from_sql', 'database_target_type','oracle.sysman.eml.ip.render.elem.HeaderParamController',
1);
Insert into SYSMAN.MGMT_IP_ELEM_PARAM_CLASSES
(ELEMENT_NAME_NLSID, ELEMENT_TYPE_NLSID, ELEMENT_PARAM_CLASS, DISPLAY_ORDER)
Values ('target_user_table_from_sql', 'database_target_type', 'oracle.sysman.eml.ip.render.elem.SQLStatementParamController', 2);
Commit;
Then you get ja new target type on the Report page in enterprise Manager.
"target_user_table_from_sql".
Then you write sql scripts which are executet at the Target database.
