Failed to parse date/time format

[Quix0r]

I get the following exception when trying to parse a ODS file:

Fatal error: Uncaught Exception: DateTime::__construct(): Failed to parse time string (1900-01-08T00:57:35.9999999999) at position 0 (1): The timezone could not be found in the database in /bla/foo/third-party/phpspreadsheet/src/PhpSpreadsheet/Reader/Ods.php:533

The file contains personal data so I cannot attach it.

The 9999999999 is extremely suspicious to me. Did you have a look a the raw file manually to see what was the exact original content ?

I'd bet it is an invalid odd file.

Closing for lack of feedback.
