About the System Clock

Each Cisco Unified MeetingPlace Application Server has a system clock that is independent of the time zone. In a failover deployment, the system clocks on the active and standby Application Servers must be synchronized with each other.

The system clock should always be set to match UTC (also called GMT). If the system clock is not consistent with UTC, then the system will not behave as expected. To display the time and date of the system clock in UTC, enter date --utc in the Application Server CLI.

Caution Do not change the system clock to correct for time zone issues. Doing so can result in long-term system problems. If the available time zone options do not work for you, then contact Cisco TAC.

Recommendations for Time and Time Zone Configurations

•Keep the following default configurations:

–Web Servers and Hardware Media Servers use the Application Server as the NTP server.

–(For Cisco WebEx integration) If you install a Cisco WebEx Node for MCS, then the Application Server is automatically configured to use the Cisco WebEx Node as the NTP server. This synchronizes the time between the Cisco Unified MeetingPlace system and the Cisco WebEx site.

•If your deployment does not include the Cisco WebEx Node for MCS, then configure NTP for the Application Server using an accurate external time reference. The NTP server should reference an atomic clock or satellite receiver.

•Configure the clocks, time zones, and NTP correctly during installation.

Post-installation changes, especially to the system clock on the Application Server, may corrupt existing meeting data on your system, such as meeting start and end times, overbook port availability, and log messages.

Configuring NTP on the Web Server

Note•This topic does not apply to Web Servers in a domain. If your Web Server is in a domain, then instead see Configuring NTP on a Web Server in a Domain.
•This topic does not apply to deployments in which users schedule meetings from the Cisco WebEx site. For information about Cisco WebEx integration deployments, see the Planning Guide for Cisco Unified MeetingPlace at http://www.cisco.com/en/US/products/sw/ps5664/ps5669/
products_implementation_design_guides_list.html.

Cisco Unified MeetingPlace automatically sets up the Web Server to use the Application Server as the NTP server for clock synchronization. We recommend that you keep this default configuration, but if you need to synchronize the Web Server with an alternate NTP server, then use this procedure to do so.

Before You Begin

•Read the "Recommendations for Time and Time Zone Configurations" section.

•By default, NTP uses UDP port 123. If your Web Server is in the DMZ and your Application Server is not, you will have to open UDP port 123 inbound in your firewall for the default NTP configuration to work. In the default configuration, the Web Server clock is synchronized with the Application Server as the NTP server.

•If you decide to use an alternate NTP server for your Web Server time synchronization, make sure that your NTP setup keeps the Application Server and Web Server perfectly synchronized with each other. If the time is not synchronized between the two servers, certain features will not work.

Procedure

Step 1 Stop the Cisco Unified MeetingPlace Web Master Service.

Step 2 Select Start > Settings > Control Panel.

Step 3 Double-click Date and Time.

Step 4 Select the Internet Time tab.

Step 5 Check the Automatically synchronize with an Internet time server check box.

Step 6 Select or enter the FQDN of the NTP server in the Server field.

Step 7 Select Update Now.

Step 8 Select OK.

Step 9 Start the Cisco Unified MeetingPlace Web Master Service.

Verifying

We highly recommend that you verify clock synchronization between the Application Server and the Web Server. To obtain the current date and time for each server:

•Application Server—Use the date command.

•Web Server—Double-click the displayed time at the bottom right corner of the Web Server desktop.

Cisco Unified MeetingPlace automatically sets up the Web Server to use the Application Server as the NTP server for clock synchronization. We recommend that you keep this default configuration, but if you need to synchronize the Web Server with an alternate NTP server, then use this procedure to do so. Before You Begin •Read the "Recommendations for Time and Time Zone Configurations" section. •By default, NTP uses UDP port 123. If your Web Server is in the DMZ and your Application Server is not, you will have to open UDP port 123 inbound in your firewall for the default NTP configuration to work. In the default configuration, the Web Server clock is synchronized with the Application Server as the NTP server. •If you decide to use an alternate NTP server for your Web Server time synchronization, make sure that your NTP setup keeps the Application Server and Web Server perfectly synchronized with each other. If the time is not synchronized between the two servers, certain features will not work. Procedure Step 1 Stop the Cisco Unified MeetingPlace Web Master Service. Step 2 Select Start > Settings > Control Panel. Step 3 Double-click Date and Time. Step 4 Select the Internet Time tab. Step 5 Check the Automatically synchronize with an Internet time server check box. Step 6 Select or enter the FQDN of the NTP server in the Server field. Step 7 Select Update Now. Step 8 Select OK. Step 9 Start the Cisco Unified MeetingPlace Web Master Service. Verifying We highly recommend that you verify clock synchronization between the Application Server and the Web Server. To obtain the current date and time for each server: •Application Server—Use the date command. •Web Server—Double-click the displayed time at the bottom right corner of the Web Server desktop.

Complete the following tasks in the order shown: 1. Pointing the Domain Controller to the External NTP Source 2. Changing the Registry Setting Manually on the Web Server Pointing the Domain Controller to the External NTP Source Before You Begin •Read the "Before You Begin" section. •This procedure is completed on the Domain Controller that includes the Cisco Unified MeetingPlace Web Server as part of its domain. Procedure Step 1 Open a command prompt. Step 2 Enter net stop W32Time. Step 3 Enter w32tm /config /manualpeerlist:NTP-server /syncfromflags:manual /reliable:yes /update An example of an NTP server is clock.cisco.com. Step 4 Wait for the previous command to complete successfully. Step 5 Enter net start W32Time. Step 6 Enter w32tm /stripchart /NTP-provider /samples:2/dataonly. Step 7 Verify that the command output shows no difference between the local time and the external NTP provider time. What to Do Next Proceed to Changing the Registry Setting Manually on the Web Server. Changing the Registry Setting Manually on the Web Server Before You Begin •This procedure is completed on the Cisco Unified MeetingPlace Web Server that is part of the domain. •Complete Pointing the Domain Controller to the External NTP Source. •Export the current registry key to a flat file. The registry key is located at HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Parameters. Procedure Step 1 Open a DOS command window on the Web Server. Step 2 Enter net stop W32Time. Step 3 Enter w32tm /unregister. Step 4 Enter w32tm / register. Step 5 Change the value of the registry setting "HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type" to NT5DS. Initially, this will be set to NTP. Step 6 Enter net start W32Time. Step 7 Enter w32tm /dumpreg to verify that all of the registry settings are correct. Do not expect the Web Server to match the external NTP source immediately after starting the w32time service. Synchronizing the time between the two systems will occur gradually. Related Topics •Troubleshooting Time and Time Zone Issues for Cisco Unified MeetingPlace module •Stopping, Starting, or Restarting the Cisco Unified MeetingPlace Web Master Service module Synchronizing the Time Between the Web Server and the NTP Server Via the Web Master Service and Windows Time Service At each Web Master Service restart or Web Server reboot, the Web Server software invokes the Windows Time Service to synchronize the time with the NTP server. This synchronization occurs regardless of the time difference. Once the Web Master Service is started, the Web Server time is synchronized with the NTP server every hour, but only if the time difference is 30 seconds or less. To synchronize the time between the Web Server and the NTP server, complete the following tasks in the order shown: 1. Verifying That the Windows Time Service is Running 2. Restarting the Web Master Service in the Stopping, Starting, or Restarting the Cisco Unified MeetingPlace Web Master Service module Verifying That the Windows Time Service is Running Procedure Step 1 Go to the Windows Start menu on the Web Server. Step 2 Select Settings > Control Panel > Administrative Tools > Services. Step 3 Find the Windows Time service. Step 4 Make sure that the Startup Type for the Windows Time service is Automatic. If not, then do the following: a. Double-click Windows Time. b. Select Automatic in the Startup type field. c. Select OK. Step 5 Verify that the Status for the Windows Time service is Started. Proceed only if you do not see "Started" in the Status column for the Windows Time service. Step 6 Right-click Windows Time. Step 7 Select Start. Step 8 Verify that Started now appears in the Status column for the Windows Time service. What To Do Next If you are trying to synchronize the time between the Web Server to the NTP server, then proceed to Restarting the Web Master Service in the Stopping, Starting, or Restarting the Cisco Unified MeetingPlace Web Master Service module.
