Standard seconds are defined based on measurable properties of a cesium atom. The historical definition of 1/86400th of a day doesn’t work for science if the duration is inconsistent.
For example the statement:
Earth’s Days Are Getting 2 seconds Longer Every 100,000 Years
becomes self-referencing and loses all meaning without some other reference point.
