To me the most intriguing part of the topic is that while multiple ways of time tracking (e.g Lunar based calendar, Tropical, Solar and Sidereal year) can be traced back to natural phenomenon, the concept of “hour” was actually entirely man made. Besides the structured time-keeping method, Johanna Drucker also mentioned how time can be described through relations and temporality. It is possible to view time from highly subjective perspectives or multiple view points.
