OpenVMS[TM] Delta-Time Limit Notification Cover Letter
AV-R4Y1A-TE
February 1997
Dear OpenVMS Customer,
The OpenVMS operating system has a documented delta-time limit
that may cause a serious error in some applications and OpenVMS
components beginning on or around 19-MAY-1997. DIGITAL has
provided ECOs (Engineering Change Orders) that remove the delta-
time limit.
Applications and OpenVMS components most likely to experience
errors are those that pass delta-time arguments with values
exceeding 9999 days on system-supplied date routines. The most
likely date that these errors will occur is 19-MAY-1997:00:00,
which is 10,000 days after the common UNIX time origin of 1-JAN-
1970.
DIGITAL strongly recommends that all customers running the
affected versions of OpenVMS install the appropriate ECO, as
follows:
For OpenVMS Alpha Version 6.1 through Version 7.0: ALPLIBR05_070
For OpenVMS VAX Version 5.5 through Version 7.0: VAXLIBR06_070
Systems running OpenVMS Alpha Version 7.1 and OpenVMS VAX Ver-
sion 7.1 are not affected and do not need to install the ECO.
The following OpenVMS components and software products are known
to be affected by the delta-time limit. The ECOs correct the
problems observed in these products.

Other software products running on OpenVMS might also experi-
ence errors stemming from this delta-time limit. Contact the
appropriate software vendor for more information.
Impact on Application Developers
Application developers and their customers must install the
appropriate ECO.
If an application developer uses OpenVMS shareable images,
there is no required code change and relinking is not necessary;
installing the ECO on the customer system corrects the problem.

Impact on Application Developers
Application developers and their customers must install the
appropriate ECO.
If an application developer uses OpenVMS shareable images,
there is no required code change and relinking is not necessary;
installing the ECO on the customer system corrects the problem.
If an application developer does not use OpenVMS shareable
images (that is, links using STARLET) and the application is
subject to the 10,000 day restriction, no code change is re-
quired. However, the developer must relink the application after
installing the ECO and might need to redistribute the software.
The application developer's customers must also install the ECO
on their systems.
If your application calls the following OpenVMS RTL Library
(LIB$) routines, you may encounter errors due to the 10,000 day
delta-time limit.
LIB$CVT_TO_INTERNAL_TIME LIB$SUB_TIMES
LIB$CVT_FROM_INTERNAL_TIME LIB$MULT_DELTA_TIME
LIB$CVTF_TO_INTERNAL_TIME LIB$MULTF_DELTA_TIME
LIB$CVTF_FROM_INTERNAL_TIME LIB$CONVERT_DATE_STRING
LIB$CVT_VECTIM LIB$ADD_TIMES
Applications that are written in DEC C and contain portable code
that calls only ANSI time functions are not impacted.

| Mark,
Also I believe you can get a more detailed description at
http://www.openvms.digital.com
The customer would like to get a similat article as the one
provided by the RDB group , it's in RDB_70 , note 9.33
They are looking for some kind of offical response/article for RALLY
Thanks in advance
Michel

| Michael,
Rally itself should not have a problem with the delta time bug. We
use our own internal date routines so we remain platform independent.
I also searched our source code and do not call any of the ten RTL
calls listed in .2.
Naturally, we can't be help responsible for any calls to ODI or EPL
routines that might invoke routines that the problem would occur or
for any other VMS products that might be called from Rally.
