I ran a test batch job that checked its own log file revision date a few times (with WAIT commands between checks), and found that the same thing occurred - log file output (followed by RDT check after log file was closed):
$ search TEST_20060712.LOG "revised:"
REVISED:12-JUL-2006 10:48:50.02
REVISED:12-JUL-2006 10:48:50.02
REVISED:12-JUL-2006 10:48:50.02
REVISED:12-JUL-2006 10:48:50.02
$ write sys$output f$file_attributes("TEST_20060712.Log","RDT")
12-JUL-2006 10:54:50.04
I ran the same procedure on a VMS 7.3-1 system and received the results that I had expected - i.e., the revision date is updated each time the log file is updated:
$ search TEST_20060712.LOG "revised:"
REVISED:12-JUL-2006 10:41:38.36
REVISED:12-JUL-2006 10:43:38.36
REVISED:12-JUL-2006 10:45:38.38
REVISED:12-JUL-2006 10:46:38.35
$ write sys$output f$file_attributes("TEST_20060712.Log","RDT")
12-JUL-2006 10:47:38.39
Also, while restoring the saveset mentioned earlier (created on VMS 7.3-1 system) over on the VMS 7.3-2 system, I noticed unusual file RDT's (many days in the past, not the actual RDT) - which differs from what I have experienced on 7.3-1.
Any information on why I am seeing different RDT behavior on VMS 7.3-2 would be greatly appreciated.

Re: File revision dates in VMS 7.3-2
RDT 12-JUL-2006 17:38:58.86
RDT 12-JUL-2006 17:39:00.86
RDT 12-JUL-2006 17:39:01.86
RDT 12-JUL-2006 17:39:02.86
Is there any difference in disk setup, e.g. ODS-2 versus ODS-5 ...between 7.3-1 and 7.3-2?
regards Kalle

Re: File revision dates in VMS 7.3-2
CSC just passed on the response from engineering on this: it's a "feature".
However it can be turn on/off:
$set vol
The default is noaccess_date. The same qualifier exists for INIT as well.

Re: File revision dates in VMS 7.3-2
The reponses I've received thus far prompted me to look further into the differences between the volumes:
VMS 7.3-1 system:
Host-based RAID 0+1 on HSG80 disks (DPAxxx:)
VMS731_F11X V1.0 applied
Highwatermarking disabled
VMS 7.3-2 system:
Volume shadowing on EVA6000 disks (DSAxxx:)
VMS732_F11X V5.0 applied
Highwatermarking enabled
I disabled highwatermarking on the 7.3-2 DSAxxx: volume on which I've been generating the batch log files - received the same result as with highwatermarking (i.e., no RDT changes).
