[cisco-voip] Wrong time on IP Phones 7960

Mon Oct 25 21:24:01 EDT 2010

Guys,

I had the same issue with 7940,7941 and 7960,7961 phones. once I upgrade 
the phone load to SCCP41.9-0-3S Daylight savings then worked.

Load version SCCP41.8-3-3SR2S have the daylight savings issue.

The reason that Cisco did not proactively act based on your earlier case 
is probably because they are just really, really incompetent with daylight 
savings time. Have they EVER had a year where they?ve got it right? Maybe 
we should just be filing bugs for the rare occasions when it *does* work.

Here you go
Bug ID: CSCtj70240 ? not listed on site yet?
BTW the 69xx is also affected
The strange thing is that I have opened a case with TAC a month ago for 
this issue ?as I am in a +2 time zone that changes DST in last of 
September not in the last of October as other +2 areas and I just got a 
response from them today when they got more hits on that case from other 
countries??why they did not do a proactive action from my case ?and 
properly others opened cases for it?.

 An issue appeared on CUCM 7.1.x with some phones (7940 and 7960). We are 
currently trying to address this issue, and our development team is 
working on it.

 Problem Symptoms:

     Time of Day routing is one hour forward schedule.
     The display time on Cisco IP Phone models listed in the problem 
description reflect one hour behind the current local time before Daylight 
Saving Time occurs.

 Workaround/Solution

     Workaround #1
     Affected customers can choose to do nothing and wait for the time to 
automatically update.

     Workaround #2
     Time of Day Routing

     Adjust the time schedules behind one hour.

     Cisco IP Phones

        1. Choose System > Date / Time Group from CUCM Admin.
        2. Create a new Date / Time group that is one hour ahead of local 
time.
        3. Choose System > Device pool.
        4. Create a New Device pool and assign the (one hour ahead Date 
time group) to this new device pool.
        5. Assign the new device pool to the Cisco IP Phones that display 
the incorrect time.

 Note: The CUCM time updates occur automatically (dates vary per time 
zone).
 Change your Time of Day Routing and Device Pools back to the original 
Date / Time group accordingly.

Hi Reto,

Try Africa/Windhoek*. This is also GMT+1 and works for me on 7960.

Let me know if it works for you too,
Marton

Hello group

this morning we found our IP Phones 7960 showing the wrong time. They all 
switched to winter time this weekend and are now one hour behind. Other 
phone types (7961, 7970) are showing the right time.

Has anyone the same problem?

Location: Switzerland
CUCM: 7.1(3a) (7.1.3.20000-2)
Phone load 7960: P00308010100
Time Zone (CMLocal): (GMT+1:00) Europe/Amsterdam* 

We have also tried other phone loads (P00308010200 / P00308000900) with no 
success.
We have checked the Bug Tool Kit but found nothing.

Thanks for help
Reto
