Time Modeling
Time is modeled as Euclidean 1-space
, that is the line.
What does this imply?

Time Modeling
Time is modeled as Euclidean 1-space, that is the line.
We need to fix
an epoch
(origin) and a “distance”
measure (unit) to be able to date
(locate) events.
How to we define the epoch and time unit?

Time Modeling
Time is modeled as Euclidean 1-space, that is the line.
We need to fix
an epoch
(origin) and a “distance”
measure (unit) to be able to date
(locate) events.
Both the epoch and time unit are defined by
conventions. The epoch is chosen to be a particular
event in time and is well defined (e.g Nov 17, 1858 at
midnight).
