On my timeline I have 100 some files on 30 Dec 1890?
The files there are a random collection - many part of recently added NEF files.
Log shows only problems with a text file - which happens to be on this 1890 timeline.
Log attached.
Metadata analyst does not show anything which does not also appear on non-included files.
What does the "Date Subject Created" for these files show in the MD Panel?
Or the {File.DateTime} variable?
30. Dec 1899 is a fallback when all timestamps are invalid.
Probably related to https://www.photools.com/community/index.php/topic,13320.0.html
Does this still happen with IMatch 2023.1.10?
1. Write the files back, if needed.
2. Select the files in a File Window, press Shift+Ctrl+F5 and then select Reload Metadata.
Sorry, can't check. I had fixed it by running the rebuild timeline option.
OK. Open a new ticket when this happens again.
