CCM updates for timezone change?

[Erick Bergquist]

Are there going to be any Cisco OS or CCM updates for the DST timezone changes coming up , or do people just follow the methods in the MS knowledge article?

Well, with 4.0(2a) they could update to 4.1(3) or 4.2(3).

Is there an issue that will be noticed on systems that are not updated other then the time not changing/adjusting on it's own correctly?

Would call manager date/time features be effected without the CCM updates? IE: How crucial is it for the CCM updates if they are on earlier versions?

If you are using a NTP server for CCM and IPCC, do you still need the patches. I am assuming yes in the event you lose connectivity to the NTP server.

I also found out that for IPCC Express/CRS, there's going to be a notice from cisco going out in a week or so with details.

In short, TAC had told me that IPCC Express/CRS 3.5(4)SR2 will have fix, and anything lower will need to be upgraded. The 3.5(4) SR2 will have a JRE update also for the DST changes.

IPCC 4.0(1), 4.0(2), 4.0(3), 4.0(4), 4.5(1), 4.5(2) will need the OS update and Sun JRE DST patch.

NTP hands out UTC only, the OS performs the DST offset calculations from it's own data.

Can someone explain how Cisco decided to bypass the fix for 4.0.2a.

What about other Unified servers? IPCC Express? Meetingplace Express? Ops Manager?

Cisco Just released this...I'm using this currently as a map for 2007 Energy Policy Act

For all CCM and IPCCX, there is ntp server loaded automatically after Cisco application is installed. The time sync path is, IPCC get sync'ed from CCM, CCM Subsriber gets sunc'ed from publisher, and publisher sync with its' local time.

So for the DST, all servers have to be updated with new DST dates, either tzedit.exe or Windows patches shall work.

With this document (http://www.cisco.com/en/US/customer/tech/tk648/tk362/technologies_tech_note09186a00807ca437.shtml) it is apparent that those customers running 4.0(2a) don't have a solution to this issue.

I'd like to understand why it is necessary to have a CallManager patch in the first place. Why would the OS patch (CSCsf07541) be tied to a version of CallManager? What are the dependencies with respect to DST/Timezones and when they begin and end for CallManager and Windows. Why is 4.0(x) not included?

Any guidance will be appreciated.

Thank you.

A new single patch for the Daylight savings was released the day before yesterday, you can find it on CCO:
