What does newermt mean in find command

command linefind

I know I can use this option to find file between particular modified times. But I'm curious about what does this mean?

I used man find | grep newermt trying to find something. But I got no direct content. It seems -newer file and mtime stuff may have relation with it. But I'm not sure..

So, what does -newermt actually mean?

find(1):

-newerXY reference
          Compares the timestamp of the current file with reference.   The
          reference  argument  is  normally the name of a file (and one of
          its timestamps is used for the comparison) but it may also be  a
          string  describing  an  absolute time.  X and Y are placeholders
          for other letters, and these letters select which time belonging
          to how reference is used for the comparison.

          a   The access time of the file reference
          B   The birth time of the file reference
          c   The inode status change time of reference
          m   The modification time of the file reference
          t   reference is interpreted directly as a time
