How To Change The Time On An Avaya Phone: A Comprehensive Administrative Guide
Adjusting the time and date settings on an Avaya phone is primarily handled through the centralized PBX server, such as Avaya Aura Communication Manager or IP Office, rather than local handset menus. Because Avaya endpoints derive their time synchronization from the network time protocol (NTP) source managed by the system administrator, manual overrides are restricted to ensure enterprise-wide consistency.
Prerequisites and Administrative Requirements
Before attempting to modify time settings, you must understand the architecture of your specific Avaya deployment. Avaya systems are generally categorized into two primary environments: the IP Office platform (common for small-to-medium businesses) and the Aura Communication Manager (common for enterprise environments). In both instances, the handset itself acts as a client that fetches time data from a gatekeeper or SIP registrar.
- Essential Access Requirements: You must possess administrative credentials (usually via Avaya IP Office Manager, Web Manager, or the System Administration Tool) to gain elevated access to the core server.
- System Configuration Prerequisites: Verify that your system is configured to sync with an external NTP server to prevent time drift.
- Hardware Scope: This guide applies to common Avaya H.323 and SIP desk phones, including the 9600 series, 1600 series, J100 series, and J100 series IP phones.
- Estimated Duration: Configuration changes in the PBX software typically take 5 to 10 minutes, though synchronization across all handsets may take an additional 60 seconds depending on network load.
Procedural Workflow for Modifying System Time
The time displayed on your desk phone is a reflection of the system server's internal clock. If the time is incorrect on one phone, it is likely incorrect on all phones. If you are an end-user and do not have access to the server, contact your IT department, as local user modification is usually disabled by administrative policy.
Step 1: Accessing the IP Office Manager Interface
If you are operating an IP Office environment, launch the IP Office Manager application on your workstation. Connect to the Control Unit by selecting the File menu and clicking Open Configuration. Provide your administrative credentials when prompted. Navigate to the System tab in the configuration tree located on the left-hand pane.
Step 2: Configuring the Time Server Settings
Within the System menu, locate the System tab and look for the Time Server field. If you are syncing to an external time source, ensure the IP address of your NTP server is correctly input in the SNTP Time Server IP Address field. To adjust the time manually, check if the system allows for manual override, though this is discouraged in favor of NTP.
Warning: Modifying the system time during peak business hours can disrupt call logging, voicemail timestamps, and presence status. Perform these adjustments during a scheduled maintenance window to ensure data integrity.
Step 3: Modifying Time Zone and Daylight Savings
Often, the time is correct on the server but appears incorrect on the handset due to improper Time Zone configuration. Navigate to the Regional settings within the System tab. Ensure the Offset from UTC is correctly set for your specific geographic region. Verify that the Enable Daylight Savings Time checkbox is marked, and confirm the start and end dates correspond to your local legal requirements for seasonal time shifts.
Step 4: Applying Changes and Resetting Endpoints
Once the adjustments are verified, click the Save icon in the toolbar. You will be prompted to select a reboot method. For time settings to propagate effectively, you may need to select Merge if the system supports it, or perform a reboot of the control unit if major system-wide time synchronization is required. To force a handset to update immediately, unplug the ethernet cable from the back of the phone and plug it back in, forcing the device to re-register with the server and pull the updated time string.

Technical Specifications and System Parameters
The following table summarizes the differences in time management protocols across common Avaya deployments.
| Feature Type | IP Office Deployment | Aura Communication Manager |
|---|---|---|
| Time Sync Protocol | SNTP (Simple Network Time Protocol) | NTP (Network Time Protocol) |
| Configuration Method | IP Office Manager / Web Manager | System Access Terminal (SAT) |
| Sync Hierarchy | Local PBX as NTP client | Multi-tiered server hierarchy |
| User-Level Access | Restricted/Read-Only | Restricted/Read-Only |
Common Administrative Failures and Field Remedies
Correcting time errors requires systematic isolation of the root cause. If your system time remains inaccurate despite your configuration changes, investigate the following failure scenarios.
- Root Cause: NTP Server Connectivity. The PBX server is unable to reach the external time source (such as pool.ntp.org), causing it to revert to a default or drifting clock.
- Actionable Fix: Verify firewall rules to ensure UDP port 123 is open for bidirectional traffic between your PBX and the designated NTP server.
- Root Cause: Incorrect Time Zone Offset. The time sync is successful, but the handset is calculating the time based on an outdated UTC offset.
- Actionable Fix: Review the Regional settings in the System menu and ensure the "Daylight Savings" rules are mapped to the current legislative calendar for your region.
- Root Cause: Stale Configuration Data. The phone has cached the old time string and is failing to query the server for an update.
- Actionable Fix: Perform a hard reset of the desk phone. Disconnect the power source (or PoE cable) for 30 seconds to force a full re-registration of the SIP/H.323 profile.
Frequently Asked Questions
Can I change the time directly on my Avaya handset menu?
In most enterprise environments, no. The Avaya handset is a client device that inherits its configuration from the central server. The option to change time is typically grayed out or entirely absent from the user menu to maintain synchronization across the organization.
Why is my Avaya phone showing the wrong hour?
The most common cause is an incorrectly configured Time Zone or Daylight Savings Time (DST) setting within the PBX system configuration. Even if your server receives the correct time from an NTP source, if the regional offset is wrong, the handset will display an incorrect local time.
How do I update the time after a daylight savings shift?
If your system is configured correctly with the appropriate DST start and end dates, the PBX will update automatically. If it does not, you must manually update the DST settings in the System menu of your Avaya Manager or System Administration Tool.
What should I do if the time is off by exactly one hour?
An error of exactly one hour typically indicates that the Daylight Savings Time setting is mismatched with your current date. Check the "Daylight Savings" configuration page in your PBX software to ensure the start and end dates are enabled and accurately reflect current regional laws.
Contact Your Network Administrator
If you have verified that your system settings are correct and the phones still show the wrong time, contact your internal IT support team. They are equipped to handle the back-end infrastructure updates required to correct network-level time distribution errors.
