Hi Carlos & Woodg,
I appreciate your comments and I can certainly understand the confusion. Please let me clarify my previous comment:
The Surface Pro 3 includes built-in functionality to prevent incorrect system times when the main battery is depleted. If the troubleshooting I provided on Aug 16, 2014 fails to address the system time inconsistencies, please reach out to our Surface Assisted Support.
Any other questions or concerns, please don't hesitate to visit the Community!
Best Wishes,
