Timestamp field adding extra hours

Hi All,

Please help me with below issue, I have a field with timestamp datatype and it has values as given in screen(Hue). When we try to access the same from Arcadia, some places it is adding 4 hours to it and few other it is adding 5 hours to the actual timestamp value. Any suggestion to resolve this issue, I could have add_hours with -ve hours value, if the addition is consistent but I see odd behavior. Please suggest or correct me if anything wrong I am doing.

Thank you,
Ganesh
