Possible to Correct Timestamps?

Forum / Questions & Answers

One of our sites had an issue where it wasn't syncing to our NTP server properly for a few days so all our data for those days is in UTC time instead of local. Is it possible to adjust the timestamps for this data within Canary back to local time? Or would we need to export the data, update it manually, and then backfill it?

    Hi ,

    You can insert data and overwrite data using the same exact timestamp, but if you need to shift the timestamps by a few hours, that would require an export and rewrite of the data. You would also need to remove the data files that have the "bad" data in them as there is no way to delete a time range of values from the Historian. You can only delete from a file standpoint.
