Entra.Station: Incorrect Time After Daylight Savings -... | terminalfaults.org

Technical Background:

Payment terminals rely on Network Time Protocol (NTP) or similar protocols to synchronize their internal clocks. Failure can occur due to network connectivity issues, incorrect NTP server configurations, or internal clock drift. Clock drift is exacerbated by low voltage, potentially from a failing power supply or overloaded USB hub. EMV transactions require accurate timestamps for security and compliance.

Symptoms:

The Entra.Station terminal displays an incorrect time following a daylight savings time transition.

Possible Causes:

Network connectivity problems preventing NTP synchronization.
Incorrectly configured or unreachable NTP server address.
Firewall restrictions blocking NTP traffic (UDP port 123).
Internal Real-Time Clock (RTC) battery failure or depletion.
Software bug within the Entra.Station's time synchronization module.
Corrupted or outdated timezone database on the terminal.

Solution:

1

Verify network connectivity of the Entra.Station terminal. Test with a ping to a known-good external server (e.g., 8.8.8.8).
2

Access the Entra.Station's configuration menu (consult the device manual for access instructions).
3

Navigate to the 'Date & Time' or 'NTP Settings' section.
4

Confirm the configured NTP server address is correct and reachable. Common public NTP servers include pool.ntp.org.
5

If the NTP server address is correct, attempt a manual time synchronization from the configuration menu.
6

Check the terminal's firewall settings (if accessible) to ensure UDP port 123 is open for outbound traffic.
7

If the problem persists, contact the Entra.Station's technical support for a firmware update or further assistance.

Safety Warning:

Safe Handling: Always unplug the Entra.Station from the power source before inspecting or adjusting cable connections. Avoid cable strain on power and network cables. High static electricity (ESD) conditions, particularly in dry winter environments, can damage electronic components. Ground yourself before touching the terminal.

Prevention:

Regularly monitor the terminal's time to ensure accuracy.,Ensure a stable and reliable network connection for the terminal.,Periodically verify the configured NTP server address.,Consider using a local NTP server within the network for improved accuracy and reliability.,Check power supply and replace if voltage is not within specification.

Expert Tip:

Some terminals allow for specifying multiple NTP servers. Adding a secondary NTP server provides redundancy in case the primary server is unavailable. Check the terminal's documentation for specific NTP configuration options. If time remains incorrect, power cycle the device (unplug, wait 30 seconds, replug) to reset the network connection.
