Description

Running tika-app-2.4.1.jar on the attached image, these metadata is returned:

The right value is 2022-06-16T14:18:49Z. Although there is no timezone specified for some values, I think it makes no sense converting them to timezones different than GMT, the one used to take the picture (-03:00) or the one used to run the application (-03:00), so Tika could be making an incorrect timezone conversion on the last 3 fields.
