F. Tags Relating to Date and Time
DateTimeOriginal
The date and time when the original image data was generated. For a DSC the date and time the picture was taken
are recorded. 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 [20.H]. When the date and time are unknown, all the character spaces except
colons (":") may be filled with blank characters, or else the Interoperability field may be filled with blank characters.
The character string length is 20 bytes including NULL for termination. When the field is left blank, it is treated as
unknown.

DateTimeDigitized
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 the DateTimeOriginal and DateTimeDigitized 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 [20.H].
When the date and time are unknown, all the character spaces except colons (":") may be filled with blank characters, or else
the Interoperability field may be filled with blank characters. The character string length is 20 bytes including NULL for
termination. When the field is left blank, it is treated as unknown.
