Files have filetimes - one is the last date/time the file was written to. It is called the file mtime, most often.
If you can simply look for files that match your pattern, grab the most recent one. If those files get created every hour or so it becomes even easier.
IF you give us more information about what you are trying to accomplish - NOT how to code it - we can give you very good answers.
As presented your code would skip over copying a file because there are two newer files not one. And how do you track what the last one copied over was? You don't with your code.
Please give us more to go on.
what shell?
What OS?
what do you want to accomplish? -- not how to code it.
