5.5.2 Date and Time



If you control validity of lock activation codes and similar by time profiles, make sure that the 2N device internal date and time are set correctly.

2N access control units are equipped with a back-up real-time clock to withstand up to several days’ long power outages. Select Use time from Internet to synchronize device time with the internet time or click Synchronize with browser to synchronize the intercom time with your current PC time. 

Note

  • The device does not need the current date and time values for its basic function. However, be sure to set these values when you apply time profiles and display time of listed events (Syslog, used cards, logs downloaded by 2N HTTP API, etc.).

Practically, the 2N device real-time circuit accuracy is approximately ±0,005 %, which may mean a deviation of ±2 minutes per month. To maximize the accuracy and reliability, we recommend that you always enable the Use time from Internet function.

List of Parameters



  • Use time from Internet –  Enable the NTP server use for device time synchronization.
  • Synchronise with browser – push the button to synchronise the 2N device time value with your PC time value.



  • Automatic Detection – define whether the time zone shall be detected automatically from My2N. In case automatic detection is disabled, the Manual selection parameter is Used (manually selected time zone or Own rule).
  • Detected Time Zone – display the automatically found time zone. In case the function is unavailable or disabled, N/A is displayed.
  • Manual Selection – set the installation site time zone. Set the time shift and summer/winter time transitions.
  • Custom Rule – if the device is installed on a site that it not included in the Time Zone parameter, set the time zone rule manually. The rule is applied only if the Time Zone parameter is set to Manual.



  • Use NTP Server – enable the NTP server use for device time synchronization. The server IP address and domain name cannot be set if Use time from Internet is disabled.
  • NTP Server Address – set the IP address/domain name of the NTP server used for your device time synchronisation.
