So, to work out the timestamp to generate the reference file you can use the date command on it's own if your system supports the options like this:-
Code:
touch -mt `date +%Y%m%d%H%M%S --date='1 hour ago'` /tmp/ref_file
find trg_dir -type f ! -newer /tmp/ref_file -name "*.aud"

If your OS does not support those date arguments, then you can play with the TZ variable to acheive the same result, thus:-
Code:
#!/bin/ksh
Orig_TZ="$TZ"
Offset=`echo $TZ|cut -f1 -d "," | tr -d "A-Z"`      # Get the numeric bit
P1_TZ="${TZ%%${Offset}*}"                           # Get the first part of the TZ
P2_TZ="${TZ#*${Offset}}"                            # Get the rest of the TZ after the offset

((Offset=$Offset+1))                                # Increase the value by one hour
TZ="${P1_TZ}${Offset}${P2_TZ}"                      # Set new timezone

ref_date=`date +%Y%m%d%H%M%S`                       # Get the value based on our adjusted TZ
TZ="$Orig_TZ"                                       # Reset back to original

touch -mt ${ref_date} ref_file

find trg_dir -type f ! -newer /tmp/ref_file -name "*.aud"


Does this suit your needs? Rather than use the TZ variable, you could of course get the values from the date command and build it up yourself, just taking one away from the hours, but then you'd have to handle going back past midnight, so change of day/month/year and it would get messier.


I hope that this helps, but if not, please explain what's wrong and what you need.
