Replacing Date in the file with Create date and timestamp

Hello,
I have files that with a naming convention as shown below. Some of the files have dates in the file name and some of them don't have dates in the file name.


imap-hp-import-20150917.txt
imap-dell-gec-import-20150901.txt
imap-cvs-import-20150915.txt
imap-gec-import.txt
imap-home-depot-import.txt


So the file naming convention is:
imap-clientname-import-YYYYMMDD.txt

All I am trying to do is: to get the ClientName and Date from the file name. If the Filename does not have dates in their file name, then we put file create date and time.

Also, the output need to be written in a output file with pipe delimitation if possible.

So the output I am looking for is pipe delimitation: clientname and date


hp | 20150917
dell-gec | 20150901
cvs | 20150915
gec | "need a create file date here"
home-depot | "need a create file date here"


I tried something below to get the date. I am getting the desired output. But how to replace it with create date for the files that does not have dates in the filename.
Code:
ls -1 imap-*.txt | awk -F"." '{print $1}' | awk -F"-" '{print $NF}'

Below is the output I am getting from above code:

20150917
20150901
20150915
import
import


Thanks
