Hi @CountMeIn thanks for stopping by the community and posting about how to have the e-file confirmation letters in your time zone. The timestamp is based off the servers because it is the actual time that it is sent to the IRS. 

This would be a great suggest for the program. For suggestions and improvements like this, the ProConnect Tax Idea Exchange is the most impactful place to share your thoughts. When ideas are submitted there, other tax professionals can vote on them, which helps our development teams prioritize and plan future enhancements. Thanks for sharing and for being a part of the community.
