Audit reports on SAP BusinessObjects BI Platform 4.3 Support Pack 3 Patch 1

Hello everyone,
I’m trying to build a report on audit DB, to get the reports last access date viewed or run,
but the results that I get from the field ADS_EVENT.Start_Time is not accurate,
This the query I use:
SELECT
ADS_EVENT.Object_Name,
Convert(VARCHAR(8),ADS_EVENT.Start_Time,112),
ADS_EVENT_CATEGORY_STR.Event_Category_Name,
ADS_EVENT_TYPE_STR.Event_Type_Name,
ADS_EVENT.Top_Folder_Name,
ADS_EVENT.Object_Folder_Path,
ADS_OBJECT_TYPE_STR.Object_Type_Name,
CAST( ADS_EVENT.Start_Time AS CHAR ),
ADS_EVENT.User_Name
FROM
ADS_EVENT_TYPE_STR INNER JOIN ADS_EVENT_TYPE ON (ADS_EVENT_TYPE.Event_Type_ID=ADS_EVENT_TYPE_STR.Event_Type_ID AND ADS_EVENT_TYPE_STR.Language = ‘en’)
INNER JOIN ADS_EVENT ON (ADS_EVENT.Event_Type_ID=ADS_EVENT_TYPE.Event_Type_ID)
INNER JOIN ADS_OBJECT_TYPE_STR ON (ADS_EVENT.Object_Type_ID=ADS_OBJECT_TYPE_STR.Object_Type_ID AND ADS_OBJECT_TYPE_STR.Language = ‘en’)
INNER JOIN ADS_EVENT_CATEGORY_STR ON (ADS_EVENT_TYPE.Event_Category_ID=ADS_EVENT_CATEGORY_STR.Event_Category_ID AND ADS_EVENT_CATEGORY_STR.Language = ‘en’)

WHERE
(
ADS_OBJECT_TYPE_STR.Object_Type_Name IN ( ‘Web Intelligence’ )
AND
ADS_EVENT_TYPE_STR.Event_Type_Name IN ( ‘Run’,‘View’,‘Refresh’ )

)

what is „not accurate“ ?
examples ?!

This field is recorded in UTC time. You will need to adjust it for your time zone to compare to current time.

the date retuned is not accurate,
it’s given me false date even I checked the server date, and I run the report by myself, but the last run date doesn’t update

it’s the same server time
