DST Updates for VG224 and VG248

Unanswered Question
Feb 20th, 2007

Are there any patches or updates that we should be concerned about for DST for VG 224 and VG248 gateways?

I have this problem too.

Hi John,

Here is the info for DST changes/updates for the VG248/VG224;

Field Notice: FN - 62680 - US Daylight Savings Time Policy Change Effective March 2007 - VG248

The VG248 receives its clock from the Cisco Unified CallManager. Please upgrade the Cisco Unified CallManager server to an appropriate software version based off of the CallManager field notice.

To ensure the new clock is pulled from the Cisco CallManager immediately, please reboot the VG248 after the CallManager is patched.

From this field notice;


U.S. Daylight Saving Time (DST) Changes for 2007


Hope this helps!


EDIT: Brandon, you are too fast again for my poor typing skills :)

Thanks for the info and the links. I have a bunch of patches to apply this weekend for security updates, hotfixes, etc as well as the DST patch. I didn't see anything out there for the VG224, did you find anything?

Hi John,

Here is the info for the VG224;


New default day light savings summer-time rules from Energy Policy Act

of 2005 may cause Cisco IOS to generate timestamps that are off by one hour

Symptom : Starting in the calendar year 2007, daylight savings summer-time rules may cause Cisco IOS to generate timestamps (such as in syslog messages) that are off by one hour.

Conditions : The Cisco IOS configuration command: clock summer-time zone recurring uses United States standards for daylight savings time rules by default. The Energy Policy Act of 2005 (H.R.6.ENR), Section 110 changes the start date from the first Sunday of April to the second Sunday of March. It changes the end date from the last Sunday of October to the first Sunday of November.

Workaround : A workaround is possible by using the clock summer-time configuration command to manually configure the proper start date and end date for daylight savings time. For example: After the summer-time period for the calendar year 2006 is over, one can configure:

clock summer-time PDT

recurring 2 Sun Mar 2:00 1 Sun Nov 2:00 (This example is for the US/Pacific time zone.)

From these VG224 Release notes;


Hope this helps! Good luck (we are doing our patching/updates this weekend :)
