Korn Shell & Nawk...Filename changes

I have the following piece of code:

 
 
YESTER=`TZ=aaa24 date +%b"-"%d`
 
filelist2=$(find /export/home/gen/check/logs \( -name \*$YESTER\* ! -name \*ADM\* \) -print | tr '\n' ' ')
 
nawk -F':' '
$2 ~ /Reason/ && $3 !~ /(PASSTHRU|OCAP|FP Power Button|Bootloader Reset)/ {
split(FILENAME, a, "-")
f = a[1]
while (i = index(f, "/")) f = substr(f, i+1)
sub("\r$", "");
printf("%s %s,%s %s,%s,%s,%s,%s-%s-%s-%s-%s-%s-%s-%s-%s\n", a[5], a[6], a[2], a[3], a[4], f, $0, f, a[2], a[3], a[4], a[5], a[6], a[7], a[8], a[9])
}' $filelist2 >> $OUTPUT

which basically looks in a certain directory for files that contain the word 'Reason' and splits the filenames, extracting pertinent information. Everything was working smashingly until the beginning of the month, as the date format changed from:

 
10.7.334.245-ADM-Cisco-Jun-30-12-11-22.txt
 

to

 
10.7.334.245-ADM-Cisco-Jul--1-13-22-33.txt.

Any suggestions as to how I can modify the code to accept BOTH types of dates?

turning

 
10.7.334.245-ADM-Cisco-Jul--1-13-22-33.txt

into

 
10.7.334.245-ADM-Cisco-Jul-01-13-22-33.txt

 
YESTER=`TZ=aaa24 date +%b"-"%d | sed 's/--/-0/'`

is the trailing dot '.' expected in :

10.7.334.245-ADM-Cisco-Jul--1-13-22-33.txt.

??

No...Sorry, my mistake... it should be:

 
10.7.334.245-ADM-Cisco-Jul--1-13-22-33.txt

Okay, thanks....the only problem is I need it to accept both types of dates because once July 10th rolls around the format will be 'Jul 10' and I do not want to have to manually change the code for this. Any suggestions would be appreciated...
