only find files older than x minutes old

I am looking for a way to show files that have been created within a certain period (say anything older than 10 minutes or so). Is there a command/series of commands I can do this with? As an example, I have the following in a directory:

-rw-r--r-- 1 owner group 70175 May 16 09:10 ICO_CS11_787113367_50467914_1_CS-11.pdf
-rw-r--r-- 1 owner group 70719 May 16 09:24 ICO_CS11_787113367_50467945_1_CS-11.pdf
-rw-r--r-- 1 owner group 70617 May 16 09:30 ICO_CS11_787113367_50467971_1_CS-11.pdf
-rw-r--r-- 1 owner group 70860 May 16 09:30 ICO_CS11_787113367_50467974_1_CS-11.pdf
-rw-r--r-- 1 owner group 70342 May 16 09:31 ICO_CS11_787113367_50467980_1_CS-11.pdf
-rw-r--r-- 1 owner group 70208 May 16 09:36 ICO_CS11_787113367_50468000_1_CS-11.pdf

Pretend it's now May 16 09:40 and I do not want to see the last three files as those are within the last 10 minutes. I only want to see:

-rw-r--r-- 1 owner group 70175 May 16 09:10 ICO_CS11_787113367_50467914_1_CS-11.pdf
-rw-r--r-- 1 owner group 70719 May 16 09:24 ICO_CS11_787113367_50467945_1_CS-11.pdf

Any idea on how this can be done? I am on AIX and writing shell scripts.

May be you could create a file with a timestamp you want and use find's 'newer' option to get the files. Search the site for numerous examples.
