In our seventh episode, we are talking again to APNIC's Chief Scientist, Geoff Huston, regarding all things time.We wander through the ways that humans have measured time and discuss the challenges of current Internet timekeepers in trying to make sure time is current — a very important element when securing a network — including how to handle leap seconds and how a recent announcement of the world’s first hardware implementation of network time protocol will assist with securing time on the Internet.You can read more on Network Time Protocol (https://blog.apnic.net/tag/ntp/) on the APNIC Blog, including a post from Geoff on leap seconds: Is the Internet running late? (https://blog.apnic.net/2018/11/28/is-the-internet-running-late/)Also, check out Netnod's white paper on the world’s first hardware implementation of NTS (https://www.netnod.se/netnod-white-paper-on-the-worlds-first-nts-hardware-implementation).The views expressed by the featured speakers are their own and do not necessarily reflect the views of APNIC.
