Custom Query 1 hour out

Hello Chaps,

Have an odd issue where a custom query on the AlertStatus table is showing all alerts triggered 1 hour before they were actually triggered, I have checked the Database directly using the same query (modified) and this returns the expected results which are shown below.

Select AlertStatus.TriggerTimeStamp, AlertStatus.ObjectName,  AlertStatus.Notes

From Orion.AlertStatus

WHERE 
(AlertStatus.ObjectType = 'Node' AND AlertStatus.State <> '1')

ORDER BY AlertStatus.TriggerTimeStamp DESC

DATABASE RESULTS

CUSTOM QUERY

I have checked the time on the servers and they are all OK, So I can only assume it is something that the NPM is doing?

Any ideas on where I could start to diagnose this?
