1. A method for reducing precision timing measuring (PTM) uncertainty, the method comprising:
- resetting an elastic buffer of a first device in response to a second device linked with the first device sending SKIP (SKP) ordered sets to the first device;
initiating a PTM handshake with the second device in response to resetting the elastic buffer; and
sending PTM messages to the second device immediately after receiving the SKP ordered sets.

Abstract
Techniques for reducing precision timing message uncertainty are described herein. A method includes resetting an elastic buffer of a first device in response to a second device linked with the first device sending SKIP (SKP) ordered sets to the first device. The method also includes initiating a PTM handshake with the second device in response to resetting the elastic buffer. Additionally, the method includes sending PTM messages to the second device immediately after receiving the SKP ordered sets.
