Equivalent of mmin in MP-RAS/NCR Unix

Hi,

i created a script to look for the modified files in the last 15 minutes.
But later was told that the server that we need to implement this script is an MP-RAS (NCR Unix) server on which i found mmin option of the find command doesnt work.:wall:

Can anybody please let me know the equivalent of mmin option of linux that i can use in the MP-RAS servers? or any relevant logic that i can make use of to get all such files modified in the last 15-20 minutes? i have 40 files to keep checking for if modified in the last 15-20 minutes and pull the new data then from such files.

In practice it is usually safer to rename files after they have been processed then it is just a case of processing the unprocessed files on the next iteration (assuming you are using cron).
