Why do we care what time it is? Why does it matter if my clock doesn’t give the same time as yours? How can we make sure they do give the same time?

This talk will begin with a brief discussion of why accurate timekeeping is important in computer systems, before focussing specifically on clock drift and Allan deviation. We shall then move on to a detailed exploration of the NTP and PTP algorithms for clock synchronisation, which forms the bulk of the talk.
