More time/Daylight savings problems

I came in this morning and my phone had the right time here in Dallas. Then I started getting calls from locations that should not have gone on daylight savings about their phones showing time 1 hour ahead. I looked at their DST rules and they were correct. The one that is wrong is my time zone. I did not update it for this year and it still says to start the first Sunday on or after March 9th. So DST in my location has not started yet. The disp time shows the correct time but says it is standard time. The system platforms show the correct time but say it is daylight time. I do not see any settings in the system platforms related to DST.

At this point I don't want to correct my DST table because I think all the phones using the table will jump ahead 1 more hour. In another week it may do that on its own when it hits the schedule on next Sunday. I don't know if there is a setting in the CM platforms or CM itself that will correct what time the CM is using.

If anyone has any ideas I would appreciate hearing them

Hardware platform? Software version?
Your main server timezone?
output from Linux command?
Command: /usr/sbin/zdump -v /etc/localtime | grep 2015

Thanks for the response. I can understand the platforms needing to know the correct time. I don't see how they are configure to give it to the CM hosts. This is the web display from the active CM

Server Date/Time
The Server Date/Time page displays the current date, time and timezone.
The current time is Mon Mar 9 14:04:51 CDT 2015

and this is the disp time

DATE AND TIME

DATE

Day of the Week: Monday Month: March
Day of the Month: 9 Year: 2015

TIME

Hour: 14 Minute: 7 Second: 11 Type: Standard

Daylight Saving Rule: 1







 
CM daylight-savings-rules needs to be change from March 9 to March 8 for the current rules to work
or

You could add a new rule using March 8 and November 1
then change locations to use the new rule number

The Linux server time and zone are correct because the activation is built into the /etc/localtime file

In earlier software versions like cm4 and earlier, DST patches had to be unpacked, activated to update the /etc/localtime files.

It seems to me that you are fighting against methods of setting daylight savings

Isn't it easier to adopt a server time of UTC (or one with DST) and then use Daylight savings time rules to apply the correct timezome on a location by location basis for the "application"?

I have always wished that my computer would be as easy to use as my telephone.
My wish has come true. I no longer know how to use my telephone.
 
Thanks Tier3

I corrected the entry in the first DST table last night and the time did not jump forward another hour like I thought it might. Logged a phone out and back in to make sure. The Disp Time shows DST is on now. Amsterdam and London are now reporting they have the correct time. They are on tables 2 and 3. There is something very odd about how Avaya processes those tables. When DST started but the tables did not show to start it at any of the locations yet it just added an hour to all locations. As soon as I corrected the first entry it also started to use entries 2 and 3 correctly.
