Timestamp Section

• Only process a photo file if the creation timestamp could be properly determined: Not all photo files come with the exact same metadata, so there may be files which have certain metadata properties defined and others that don't. If this option is checked, Photo Date Adjustator will only process those files where the photo or video creation timestamp could be properly extracted. Otherwise it will not touch the file when processed, not move or copy it over into the output folder if one of these modes are selected. You can thus keep track of those files that where correctly adjusted and those that were not.
  If this option is unchecked, Photo Date Adjustator will move or copy all files.

  You can always get information about whether an individual file could be properly scanned for a proper 'creation' 'timestamp in the 'Status' column of the photo file table on the Home screen. This column also tells you after processing whether the timestamps could be adjusted correctly.

• If a photo file's media creation timestamp can't be determined, ...: 'don't use a fallback timestamp' – this option may result in photo files not getting updated. Alternatively, if you select to 'use the file's [file system] creation timestamp', the media creation timestamp will be assumed to be equal to when the actual file was created in the file system. The last possible option is to 'use a fixed timestamp' which you can then enter here.
• If a photo file's media creation time zone can't be determined, ...: 'use the current system time zone' if your video or photo was recorded in the same time zone as your Mac is currently configured. Alternatively, you can select a fixed time zone to be used as fallback information, e.g. if you know which time zone the file's content was shot. Unfortunately, video files often don't carry explicit time zone information in their metadata properties.
• Use the following alternative metadata properties when failing to automatically determine a photo creation timestamp:

  While there is some level of standardization of EXIF, TIFF and other metadata properties, by far not all camera or tool vendors comply with it. This results in different metadata property names used for the same logical information – e.g. in most cases the timestamp of when a photo was taken is stored in the EXIF property named "DateTimeOriginal" (which Photo Date Adjustator is using as the default), the timezone offset is stored in "OffsetTimeOriginal" and subsecond information resides in "SubSecTimeOriginal". But Canon, for example, has decided to store the latter in the property "TimeZone" instead, and some video formats use "CreateDate" instead of "DateTimeOriginal". In order for Photo Date Adjustator to be a bit smarter in also processing photo files in such cases, or when you figure out that your camera uses yet another metadata property, you can edit and provide further alternatives here. Photo Date Adjustator will try to look them up one after the other if the previous attempt failed.

  The first column in the list of properties are the default properties that Photo Date Adjustator relies on to understand the creation timestamp of your photo or video files. The alternative property names on the left to each placeholder are the most common alternatives found. Should you run into a situation where your photo or video files' creation date is apparently not properly detected, check if your camera perhaps stores this information with a different name. You can then add this property's name – separated by a comma – to the list of alternatives, and retry.

  If you change the list of placeholders or their alternatives, you have to reload all input files to have those changes take effect. This will not happen automatically.
