One rotation of Earth is what humans perceive as a day, and Xiao Nan's use of this description to characterize time is somewhat peculiar.
Qinsi, as expected, said, "It seems you emphasize state effects rather than a fixed concept of time."
Shen Yue understood what Qinsi meant — the concept of time is a constraint that people add to themselves. According to human concepts, time is not equal on any planet. During the traversal of spatial layers and the interaction between two worlds, time becomes as useless as a chicken rib, completely lacking in measurable significance.
Just as the microstate can no longer be measured by human metrics, Xiao Nan's use of states to calculate change clearly acknowledges this issue.
"The Heaven-mending Technique delayed the hard collision of the two worlds..."
