How can time intervals be divided into smaller sections?

edit

Time intervals can be divided into smaller sections by using units of time that are smaller than the original interval. For example, if the original time interval is 1 hour, it can be divided into smaller sections by using units of minutes (60 minutes in 1 hour) or seconds (3,600 seconds in 1 hour). Similarly, if the original interval is 1 day, it can be divided into smaller sections by using units of hours (24 hours in 1 day), minutes (1,440 minutes in 1 day), or seconds (86,400 seconds in 1 day). The choice of time unit depends on the level of precision needed for the particular task or measurement.
