Hub date and time

Review these considerations to help you configure the date and time for Lenovo XClarity One Hub.

To configure network settings, click Date and time from the context menu on the Administration view.

Time zone​

Choose the time zone where the hub 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
The hub 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 hub is set to synchronize to a different source than its host, you must disable the host time synchronization between the hub 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.
