�� v1.4.1 - Container Timezone Support

This patch release fixes timezone handling in Docker containers to properly display timestamps in the user's local timezone.

🐛 Fixed

Container Timezone Support

• Issue: Container logs showed UTC timestamps regardless of TZ environment variable setting
• Solution: Added timezone data support and configuration to Docker container
• Impact: Container now properly respects timezone settings for international users

🔧 Technical Implementation

Docker Changes

• Added tzdata package to Alpine base image for timezone information
• Maintains minimal container size while adding timezone support

Application Changes

• Implemented timezone detection and configuration in Go application
• Reads TZ environment variable and sets time.Local accordingly
• Provides confirmation logging when timezone is successfully set
• Graceful fallback with warning message if timezone loading fails

📋 Usage

With Timezone Support

docker run -e TZ=Europe/Vienna ghcr.io/drallgood/audiobookshelf-hardcover-sync:latest

The container will:

• Log: Timezone set to: Europe/Vienna
• Display all timestamps in CEST (Central European Summer Time)
• Maintain full application functionality

Backward Compatibility

• Works perfectly without TZ environment variable
• No breaking changes to existing deployments
• Default behavior unchanged for existing users

✅ Verified

• ✅ Timezone configuration working correctly
• ✅ Vienna timezone (CEST) displays properly
• ✅ UTC comparison confirms correct 2-hour offset
• ✅ Application logging shows timezone confirmation
• ✅ All tests passing (28/28)
• ✅ Docker builds successfully
• ✅ Backward compatibility maintained

🔄 Upgrade Path

This is a patch release with no breaking changes. Simply update your container image:
