Setting the XClarity Controller date and time

Use the information in this topic to understand XClarity Controller date and time settings. Instructions are provided to configure the XClarity Controller date and time. The XClarity Controller date and time is used to time stamp all events that are logged in the event log and alerts that are sent.

At the XClarity Controller home page, click the clock icon on the upper right-hand corner to view or change the XClarity Controller date and time. The XClarity Controller does not have its own real-time clock. You can configure the XClarity Controller to sync its time and date with a Network Time Protocol server or with the server’s real-time clock hardware.

Syncing with NTP

Complete the following steps to synchronize the XClarity Controller clock with the NTP server:

  • Select Sync up time with NTP and specify the NTP server address.
  • Additional NTP servers can be specified by clicking the “+” icon.
  • Specify how frequently you want the XClarity Controller to sync with the NTP server.
  • The time obtained from the NTP server is in Coordinated Universal Time (UTC) format.
    • If you want the XClarity Controller to adjust its time and date for your local region, select the time zone offset for your locale from the drop-down menu.
    • If your location observes Daylight Saving Time, tick the Automatically adjust for Daylight Saving Time (DST) checkbox.
  • When your configuration changes are complete, click Apply.

Syncing with the Host

The time kept in the server’s real-time clock hardware may be in Coordinated Universal Time (UTC) format or may already have been adjusted and stored in local time format. Some operating systems store the real-time clock in UTC format while others store the time as local time. The server real-time clock does not indicate which format the time is in. Therefore when the XClarity Controller is configured to sync with the host’s real-time clock, the user can choose how the XClarity Controller uses the time and date that is obtained from the real-time clock.

  • Local (example: Windows):

    In this mode, the XClarity Controller treats the time and date that is obtained from the real-time clock as local time with any applicable time zone and DST offsets already applied. If your location observes Daylight Saving Time, you can also tick the Automatically adjust for Daylight Saving Time (DST) checkbox.

  • UTC (example: Linux):

    In this mode, the XClarity Controller treats the time and date that is obtained from the real-time clock as Coordinated Universal Time, with no time zone or DST offsets already applied. In this mode, you can choose to adjust the time and date for your local region by selecting the time zone offset for your locale from the drop-down menu. If your location observes Daylight Saving Time, you can also tick the Automatically adjust for Daylight Saving Time (DST) checkbox.

  • When your configuration changes are complete, click Apply.
Note
When daylight saving occurs, any actions that were scheduled for the XClarity Controller to perform during the interval when the clock jumps forward will not be performed. For example, if the US daylight start time is 2:00 am on March 12th, and a power action is scheduled for 2:10 am on March 12th, this action will not occur. Once the time reaches 2:00 am, the XClarity Controller will instead read the time as 3:00 am.
