Ok.Where you find out time difference between the access point and the apps refresh time.?
As Ashfaq said stop the services through the third party person and once the proper deployment done then start the services again and recheck the time.Make sure that please check with the third person to paste the same folder.
Also please check with them after the deployment whether the one of the service like webservice is running or not.As per my knowledge if the webeservice is not running we will not see the proper time and apps at access point.
Thank you everyone for your responses and sorry for responding late for this thread.
I was facing this issue from last 2 years and didn't understand the reason for this. Since I was able to see the updated data in my report I didn't worry much about this. But recently I got to know from someone that on access point the reports will always show the date when the QVD is reloaded and not the date when the report is refreshed.
