The Complete Guide to Photo Date Management
A four-part series covering everything from basic filesystem fixes to advanced video timezone correction. Master all 14 date operations in MetaScope.
Series Overview
Managing dates in a photo library is harder than it should be. Filesystem dates get corrupted by copying. Embedded metadata disagrees across standards. Cameras record wrong timezones. Video files are ignored by most tools.
This series covers it all.
The Series
Part 1: Fix Your Photo Dates: The Basics
For everyone. The foundational operations every photographer needs.
- The filesystem date problem explained
- Copy to Filesystem — Restore dates from EXIF
- Offset File Dates — Shift dates by fixed amounts
- Real-world scenarios: drive migrations, scanned photos, cloud sync
Read time: 8 minutes
Part 2: Master Your Metadata Dates
For those with embedded metadata issues. When EXIF, XMP, and IPTC disagree.
- Understanding date standards (EXIF, XMP, IPTC, Filesystem)
- Copy to Metadata — Spread EXIF to other standards
- Offset Metadata Dates — Fix embedded timestamps
- Offset All Dates — Fix everything at once
- Sync All Dates — Make all standards agree
- Real-world scenarios: timezone disasters, inconsistent archives
Read time: 10 minutes
Part 3: Advanced Date Operations
For power users. Complex date problems require sophisticated solutions.
- Set Absolute Date — Stamp specific dates on files
- Parse from Filename — Smart pattern recognition (6 formats)
- Auto-Fix Inconsistencies — Detect and resolve mismatches
- Remove Date Metadata — Privacy scrubbing
- Interpolate Dates — Calculate missing dates for sequences
- Real-world scenarios: event archives, RAW+JPEG workflows, filename recovery
Read time: 12 minutes
Part 4: Video Dates & Timezone Mastery
For complete coverage. Video files and timezone correction.
- QuickTime metadata explained (CreateDate, MediaCreateDate, etc.)
- All operations work on MOV/MP4/M4V
- Timezone Correction — Fix offset errors properly
- Date Consistency Validation — Visual mismatch detection
- Real-world scenarios: travel video, mixed archives, UTC normalization
Read time: 10 minutes

Why This Matters
When dates are wrong, your photo timeline becomes chaos. That vacation from 2019? Finder shows 2023. Those wedding photos? Scattered across three different years. Your video clips? Can’t sort them chronologically.
Worse, different applications show different times for the same file. Photos.app says one thing. Lightroom says another. Finder shows a third.
MetaScope’s date operations give you complete control over every timestamp in your library—at the filesystem level, in embedded metadata, for photos and video, across all standards.
Getting Started
Start with Part 1: Fix Your Photo Dates: The Basics if you’re new to date management. You’ll learn the foundational operations that solve 80% of date problems.
If you’re comfortable with the basics and need to fix timezone errors or metadata inconsistencies, jump to Part 2: Master Your Metadata Dates.
Power users dealing with complex archives should head to Part 3: Advanced Date Operations for the sophisticated tools.
And if you need to work with video files or correct timezone offsets, Part 4: Video Dates & Timezone Mastery covers everything you need.
MetaScope v1.2.2 introduces the most comprehensive date management system available for macOS. 14 operations spanning photos and video, full timezone support, and intelligent consistency validation.
