What To Try First When Troubleshooting Time Issues

If you have any issues with time on your Cisco Unified MeetingPlace system, then check that time is synchronized across all your servers, for example:

Hardware Media Server with Application Server

Web Server with Application Server

Application Server with Cisco WebEx Node

System Clock Does Not Match UTC

Problem   The system clock on the Application Server does not match the true UTC time.

Recommended Action    Make sure that the time zone file UTC value is true. To check this, log in to the CLI as root and enter the cat /etc/sysconfig/clock command. Change the value of UTC to true with a text editor if it is not already set to true.

Possible Cause    System clock issues are typically caused by manually setting the system clock, which may drift compared to UTC time, or by failed communication with the NTP server.

Recommended Action    Configure NTP for the Application Server. If already configured, then verify that the NTP server is set to the correct time and is otherwise working correctly. If necessary, configure the Application Server to use a different NTP server.

(Cisco WebEx integration only) If you installed the Cisco WebEx Node, then the Application Server is automatically configured to use the Cisco WebEx Node as the NTP server. Do not modify this configuration, which ensures that your Cisco Unified MeetingPlace system clock is synchronized to Cisco WebEx site.

Possible Cause    Selecting the wrong time zone on the Application Server.

Recommended Action    Configure the correct time zone.

Possible Cause    The Daylight Saving Time rules changed, or your time zone definition is obsolete.

Recommended Action    Make sure that you apply any Cisco Unified MeetingPlace software updates that were provided for Daylight Saving Time or time zone changes.


Note When a Daylight Saving Time rule changes, you need to update all time-dependent software products in your organization, such as Cisco Unified MeetingPlace, Microsoft Exchange, Microsoft Windows, and the Microsoft Outlook plug-in for Cisco Unified MeetingPlace.

Failure to do so may cause meetings to appear to be scheduled for different times in different user interfaces. For example, a meeting scheduled in Microsoft Outlook may display the correct time in Microsoft Outlook, but may appear from the Cisco Unified MeetingPlace web user portal to be scheduled for an hour earlier or later than the correct time.

System Clock is Wrong Due to Daylight Saving Time

Problem   The time on the Application Server system clock is wrong due to Daylight Saving Time.

Recommended Action    Make sure that you have selected the correct time zone on the Application Server.

Recommended Action    Make sure that you apply any Cisco Unified MeetingPlace software updates that were provided for Daylight Saving Time or time zone changes.

Recommended Action    Synchronize your system time using a reliable, external NTP server.

System Clock is Wrong—Need to Set it to an Earlier Time

Problem   The time on the system clock is later than the correct time.

Recommended Action    Make sure that you are using the correct time zone on the Application Server.

Recommended Action    Configure NTP on the Application Server to synchronize your system clock to a reliable, external NTP server.


Note When you move the clock backwards and the system now has meetings scheduled to be held over two years from the new system date, then the system could allow too many meetings and ports to be scheduled on those future dates.

If there are only a few meetings scheduled to be held over two years from the new system date, or if they are scheduled to use a low number of ports, then your users are unlikely to be affected. If some of these meetings use a large number of ports, then we recommend that you delete these meetings and ask the owners to schedule them again if necessary.


Recommended Action    Reinstall both the Application Server operating system and the Application Server software.

Recommended Action    If the previous solutions did not work, then contact Cisco TAC.

Time is Not Synchronized Between the Application Server and the Web Server

Problem   The time is not synchronized between the Web Server and the Application Server.

Solution   If your Web Server is configured to use the Application Server as the NTP server (recommended):

1. Verify that the Windows Time Service is running.

2. Restart the Web Master Service to invoke the Windows Time Service to synchronize the time between the Web Server and the NTP server.

Solution   Make sure that NTP is configured correctly on your Web Server.
