To repair the time, click the Repair Time radio button, enter the correct time, time
zone, and region in the fields provided and click [Change Time].
„
To delete an archive file, select the archive file from the list and click [Delete].
After you delete all the files with bad timestamps, you must click [Repair]. This
regenerates the archive management table to synchronize all good archives. You
must reboot the module after deleting archive files by clicking [Reboot].
„
If you do not want to delete the archive files that have future timestamps, you can
wait until the time listed in the timestamp is no longer in the future. Once that
occurs, click [Reboot] to reboot the module. When the archives are checked
again, no future timestamps will be found in the archive files and no repair is
needed.
Once the archives are repaired, the system will be brought back to a normal state
during the next bootup.
If you choose to repair time, be aware that if you have previously synched your ME
module to an external time source such as a controller or an NTP server, clicking
[Change Time] will reset your time source to manual. We recommend, therefore, that
before you perform this step, you attempt to fix the problem with your original time
source first. Please refer to the FactoryTalk Historian ME Online Help for more
information about managing time.
Once you have deleted an archive file, you cannot choose the Repair Time option. If
you want to repair the time for the remaining archive files with bad timestamps, you
must close your browser and reopen another session in Safe Mode.
Do not power off the module when repairing the archive files. If you power off the
module during the repair, the repair will not go through and you will need to go back to
the FactoryTalk Historian ME Web Diagnostics interface to repair the archives.
If the module is rebooted and the Safe Mode page has not been refreshed, clicking
[Delete], [Reboot], or [Repair] again will result in a message telling the user that there
are no archives to repair and to go to the home or login page.
