Workflow approval stamp can't show local time

I have setup an approval workflow with stamp which stamp with approval time in DocuWare Cloud, the next step in workflow is to send the document with annotation to a recipient by email.
However the approval stamp is not correctly shown the local time (+08:00), please see the attachment of claim-transportation(email from workflow).pdf.
I check the same document in DocuWare folder and I found the time stamp is correctly shown the local time, please see the attachment of claim-transportation(from folder).pdf.

I have made few test with workflow and find the approval stamp annotation which send out by email during workflow can't show with local time, however the document which I open in DocuWare folder can stamp with correct local time.

May I have a solution to set approval (decision) stamp in DocuWare workflow with correct local time? Thanks.
