Effects of clock/calendar time
● Abstraction● Separation from
everyday activities– Primacy of monochronic
attitude
![Page 35: XCC09 Time: perception, measurement](https://reader035.vdocuments.us/reader035/viewer/2022062613/5453d9c8af795907578b578a/html5/thumbnails/35.jpg)
Polychronic & Monochronic
● Polychronic: many-things-at-once, people-oriented, integrating, transaction completion, 'less tangible', scale-limited
● Monochronic: schedule-oriented, one-thing-at-a-time, arbitrary and imposed, alienating(?), scalable
