AlphaLexman is correct. The "last modified" timestamp is the most useful and is the one used by "ls -la" and "find -mtime" etc..
The "-ctime" timestamp is the timestamp when the inode was last changed. Some backup software changes this timestamp to mark the file "backed up".
Earlier I was trying to avoid the epoch date arithmetic or writing a "C" or "perl" (or whatever) program.
There are many techniques to find files which are less than 20 minutes old even if you don't have the GNU version of "find" - which offers this sort of search as standard.
Let's find out what you are trying to do in more detail.
