Many people think about time as being provided by a 'universal calendar with a huge clock'. But that wouldn't be measurable, because time does not flow this way. Iow: there ain't no such thing as 'absolute time', which you could eventually measure. You can only use time, if you know a starting point (in time) and the local frequency of its units. As common 'starting point' we take 'birth of Jesus Christ', even if nobody knows for sure, when or whether at all or that person was born. As 'rhythm of time' we usually take the rotation of our home planet, even if that isn't perfectly stable. TH
