Polycom DST Issue

[Friedom-Tech]

Hi,

 

i have a bunch of customers using Polycom phones and every time there is a DST change I get complaints for around a week that the time on their phones is wrong because the time is changing based on the old dates for time change.

 

is there any easy way for me to update the DST date changes in all phones without having to manually log in to each and every one? (around 2-300)???

 

please advise.

What time server are you using? Dirty workaround could be to set the time locally on that time server. Are other phones doing okay with the same server?

we are hearing this as well. I think the PNP doest have the DST adjusted to the 14th.

This is in timezones.xml:

 

  <zone name="EDT">
<description>Eastern Time Zone</description>
<gmt_offset>-18000</gmt_offset>
<dst_offset>3600</dst_offset>
<dst_start_day_of_week>1</dst_start_day_of_week>
<dst_start_month>3</dst_start_month>
<dst_start_time>02:00</dst_start_time>
<dst_start_week_of_month>2</dst_start_week_of_month>
<dst_stop_day_of_week>1</dst_stop_day_of_week>
<dst_stop_month>11</dst_stop_month>
<dst_stop_time>02:00</dst_stop_time>
<dst_stop_week_of_month>1</dst_stop_week_of_month>
 </zone>

 

Not sure if that reflects the 14th?

Not sure <dst_start_week_of_month>2</dst_start_week_of_month> - start from today. Maybe they can change 2 to 3 in the timezones.xml and keep it in the 'html' folder & restart the PBX. Not sure that is the right thing to do as we are also on Eastern Time Zone & not seeing this issue.

Well the question is if it works for other phones, e.g. Cisco or snom. Maybe this problem affects only Polycom (potential offset problem)

It does reflect the 14th because it shows <dst_start_week_of_month>2</dst_start_week_of_month> which is the second week of the month.

 

where do i find this file and how can i modify it so that i will push out to all phones on reboot?

The other thing that you can do very easily is to temporarily change the time zone to something like Chicago without DST. Dirty workaround, but it should fix the problem immediately without reboot of the PBX.

This is a poor polycom design.

well my linux is set properly for DST. by timezone.xml is ok.

but pbxnsip itself is adjusted 1 hour off.

 

I temporarily fixed this by setting the PBX to MST(no DST)

 

but where is pbxnsip itself getting this timezone info?

[Vodia PBX]

The PBX gets the timezones from its own file. Using the OS does not really help, it will essentially just the time in the current time zone. Linux has a kind of database for this, but that does not help you if you want to offer the same service in Windows. Plus every phone wants it in a different way. So we started our own little timezone collection. At least it is stored in a XML file and changes are easy.

how do we edit it? seems to be wrong. or is that the above file?

 

can we load this in the web UI without having to restart the PBX?

[Vodia PBX]

We plan to make it editable in the next major release. For version 4, you could put it into the html directory and restart the service.

2) Placed into HTML folder
