About how to use the mtime parameter in the find command ~

-Mtime N: Find the file based on the change time of the file, and N is an integer.
N indicates that the file change time is n days,-N indicates that the file change time is less than N days, and + N indicates that the file change time is earlier than N days.
For example:

-Mtime-1 indicates the file modification time is less than one day, that is, the file within one day (24 hours) from the current time

-Mtime 0 indicates a file whose modification time is less than one day (24 hours) from the current time.
-Mtime 1 indicates a file whose modification time is one day, that is, a file whose modification time is one day (24 hours-48 hours.
-Mtime + 1 indicates that the file modification time is greater than one day, that is, files other than the current time two days (48 hours)
Why does-mtime + 1 indicate that the file modification time is greater than one day, that is, the file 48 hours away from the current time, instead of 24 hours away?
Because the N value can only be an integer, that is, the nearest integer greater than 1 is 2, all-mtime + 1 is not greater than 1 day (24 hours) than the current time ), it is more than 2 days (48 hours) than the current time ).
