Date & Time
DateTimeOriginal & Timezone Metadata on Mac
DateTimeOriginal, CreateDate, and ModifyDate often disagree after edits, imports, travel, and timezone shifts. Filenames alone are not a clock of record.
When DateTimeOriginal looks wrong on the Mac, compare camera time, file-system stamps, and—for video—QuickTime creation atoms. Crossing time zones, daylight-saving changes, and catalog imports that rewrite ModifyDate are common causes of “off by hours” shot lists.
Mac inspection clarifies which clock a file actually claims before you sort a wedding day, rebuild a legal hold, or migrate an archive. Prefer DateTimeOriginal for many camera stills, but verify against your pipeline and MWG guidance when fields conflict.
MSAM.media apps—ExifTool Reader, ExifTool Reader Pro, and EXIF Exporter Pro—run on macOS and are sold only through the Mac App Store. Use them to inspect date fields locally and export selected columns for shot lists. Correcting clocks belongs to your editing or catalog tools after you know which tag is wrong.
