Another big issue is how time is often used to determine the order of events. Did event1 occur before or after event2?
Things like timestamps are used to track things like file creation, transaction processing, and other digital events.
As computers and networks have become increasingly fast, the accuracy of the timestamps becomes more and more critical.
While the average human doesn't care if a file was created at a time calculated down to the nanosecond; it is often important to know if it was created before or after the last backup snapshot.
