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.

ctxtools
CTXTOOLS(1) ConTeXt CTXTOOLS(1)
NAME
ctxtools - clean up temporary ConTeXt files, install latest ConTeXt
SYNOPSIS
ctxtools [ OPTION ... ]
DESCRIPTION
ctxtools is useful for dealing with ConTeXt source and generated files and for installing new versions of ConTeXt.
OPTIONS
--help Print the available options.
--purgefiles
Get rid of many temporary files generated by ConTeXt. You can give the --all option to remove a larger fraction of those files, and
the --recurse option to remove these files also in subdirectories.
--contextversion
Show the date of the ConTeXt macros and the format file. Useful after upgrading ConTeXt (perhaps using --updatecontext) to check
whether the new formats and macros are visible to the TeX path searches (see kpsewhich(1).
--updatecontext
Download the latest ConTeXt distribution and install it in the TEXMFLOCAL tree (see kpsewhich(1) for information on TeX path search-
ing). TEXMFLOCAL usually points to a system-wide location. If you want to install the new ConTeXt in your home directory (i.e. an
install for one user), then set the TEXMFLOCAL environment variable while running ctxtools. For example, using the syntax of the
Bourne shell sh(1):
TEXMFLOCAL=$HOME/texmf ctxtools --updatecontext
--documentation
Generate a .ted file from the source file. See also the --module option to texexec(1).
--patternfiles [languagecode]
Generate pattern files. You can also give the --all, --xml, and --utf8 options.
ENVIRONMENT
TEXMFLOCAL
Used by --updatecontext to decide where to install the distribution.

texexec(1), texmfstart(1).
