View and edit the current time

To view and edit the current time in FactoryTalk Historian ME
  1. Click the
    Advanced
     tab, and then click
    Time Management
    .
    The
    Time Management
     page appears.
    You can view the module's current time in the
    Module's Current Time
     box.
  2. Select one of the time synchronization options:
    • Controller Time
      In the list, select a controller or a shortcut to a local controller which will be used for time synchronization.
      TIP:
      The Logix Designer installation DVD contains the Logix Designer Clock Update Tool. The tool lets you view and synchronize the system time of the controllers and devices on a network, using any computer with a Microsoft Windows operating system and RSLinx Classic installed. For details, see the Logix Designer Clock Update Tool online help.
      If you use a shortcut to a local controller as the time source, and this shortcut or the controller to which the shortcut is pointing is removed, an error message appears informing you that this time source is no longer available.
    • NTP Server
      In the box, type the IP address or the hostname of the NTP server computer which will be used for the time synchronization.
      For details on using this option, see Considerations for using an NTP server as the time source.
    • Manual Set
      In the box, type the new time in the same format as the one displayed in the
      Module's Current Time
       box. The time is kept by the module's real-time clock.
      TIP:
      With this option selected, the module's time is not synchronized with any time source. As it may result in a potential drift of the real-time clock over time, the
      Manual Set
       option should only be used in rare cases such as demonstrations or troubleshooting associated with maintenance.
      For details, see Clock drifts.
  3. Click
    Save
    .
    The module is automatically rebooted, and the updated time is displayed in the
    Module's Current Time
     box.
    TIP:
    The time on the selected time source may be in the past compared to the current module time. Using such a time source will cause the module time to be in the past, and will cause the module to reboot into safe mode. In such a case, you need to repair the archive files and get the module out of safe mode.
