MYSQL connection Date problem

I guys,

I have a power BI report which one of it's source is a MYSQL Database. 
The query has a field "created_at" which is a datetime field.

 

When iam refreshing the report sometimes power bi subtracts one hour to that field, sometimes it gave the correct value.

 

Have you guys face someting similar to this ? 

 

Any  problem with the connector ? 

 

Iam running out of ideas, please help.

    Its strange that  PBI is subtracting one hr from source data and it shoudlnt be. You say that sometimes it works correct, do you see any particular pattern when its manipulating date and when its pulling correct?

      Do you have sample data snapshot of

      1. When its pulling correct data

      2. When its subtracting 1 hr.

       

      Basically am trying to understand in what scenrieo it happens.

       

      Thanks

      Hi Anonymous,

       

      There is my  M script on Power BI:

       

      let
      Source = MySQL.Database("xxxxxx", "xxxxxx", [ReturnSingleDatabase=true, Query="SET SESSION TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;#(lf)SELECT SO.id #(tab)#(tab) #(tab) #(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)as sale_id,#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(lf)#(tab) SO.identification #(tab) #(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)as sale,#(lf)#(tab) SO.created_at #(tab) #(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)#(tab)as date#(lf)FROM orders SO#(lf)WHERE 1=1#(lf)AND SO.state_id in (2,4,5);#(lf)SET SESSION TRANSACTION ISOLATION LEVEL REPEATABLE READ ;#(lf)"]),

      in
      #"Source"

       

      And then when i refresh the query several times on the query editor it has that strange behavior ( sometimes it has the correct result, others it retrieve date with one hour early). Same behavior its happening outside query editor.
