dateTimeDigitized property
The date and time when the image was stored as digital data. If, for example, an image was captured by DSC and at the same time the file was recorded, then {@link #TAG_DATETIME_ORIGINAL} and this tag will have the same contents. The format is "YYYY:MM:DD HH:MM:SS" with time shown in 24-hour format, and the date and time separated by one blank character ({@code 0x20}). When the date and time are unknown, all the character spaces except colons (":")should be filled with blank characters, or else the Interoperability field should be filled with blank characters. When the field is left blank, it is treated as unknown.
Implementation
final String? dateTimeDigitized;
