Achieving Causality with Physical Clocks
Sandeep S. Kulkarni, Gabe Appleton, Duong Nguyen · 2022
Physical clocks provide more precision than applications can use. For example, a 64 bit NTP clock allows a precision of 233 picoseconds. In this paper, we focus on whether the least significant bits that are not useful to the applications could be used to track (one way) causality among events.
