On-premises portal date and time

Review these considerations to help you configure the date and time for the portal when running XClarity One on premises.

To configure date and time settings, click Portal configuration on the context menu from the Settings view, and then locate the Date and time panel.

Time zone​

Choose the time zone where the portal host is located.

If the selected time zone observes daylight saving time (DST), the time is automatically adjusted for DST.

NTP server​

You must set up at least one and up to four Network Time Protocol (NTP) servers to keep timestamps synchronized across the XClarity One portal, hubs, and all managed devices. XClarity One uses systemd’s SNTP client for time synchronization, with support for NTP v3 and v4.

Attention

  • If the timestamps are not synchronized between the portal and the authentication server, sign in requests using the one-time passcode might fail.

  • If the timestamps are not synchronized between the portal and the hub, you might lose connection to the hub.

  • The portal and its host must be set to synchronize to the same time source to prevent inadvertent time mis-synchronization. Typically, the host is configured to have its virtual appliances time-sync to it. If the portal is set to synchronize to a different source than its host, you must disable the host time synchronization between the portal and its host.

Each NTP server must be accessible over the network.

If you change the time on the NTP server, it might take a while for the hub to synchronize with the new time.
