As part of an SF writing project, I would like information on the accuracy of computer system logs, worldwide. One could think of a global map that had a tiny dot for every computer or phone that would indicate the precision of each device. I am more interested in precision (basically measuring the intervals) but information on absolute accuracy is also welcome. For example, when I look in my MAC console, I see precision apparently to a microsecond.
Also of interest:
- High end, government scientific machines that record much higher precision?
- GPS spatial precision for given time precision?
Thanks for any help
Here is an edit after many comments, hoping to address issues mentioned.
Prior to this post, I had found: https://www.iol.unh.edu/sites/default/files/knowledgebase/1588/ptp_overview.pdf
The idea was to ask the question: If I could access every computer device in the world (servers, phones, workstations, laptops, ..., excluding things like fridges) and I mined the, for each device, the most accurate timestamp for a common event (assume that event stamps at the accuracy that the device would normally write to the highest accuracy log), what would the histogram of timestamp accuracy look like. Based on the reference above, I guessed that most would be at the 10 millisecond level, a sizeable number at the 10 microsecond and a few at the 10 nanosecond level. A map of the accuracy, plotted over the world, would look noisy but with the definite hierarchy above. My question is: is that a correct picture and is the accuracy truly limited in such an experiment to 10 ns?
I regret not posting the reference in the original question.
Regarding the GPS question, please ignore it as, rereading, it confuses even me.
I post on world building because, in my experience, if I posted od other forums, they would direct me here.
