+# 타임존 설정 작업 계획
+
+## 개요
+프로젝트 전체에 서울 타임존(Asia/Seoul, UTC+9)을 일관되게 적용합니다.
+
+---
+
+## 현재 상태
+
+### 완료된 설정
+| 구성 요소 | 상태 | 비고 |
+|----------|------|------|
+| **MySQL 데이터베이스** | ✅ 완료 | DB 생성 시 Asia/Seoul로 설정됨 |
+| **config.py** | ✅ 완료 | `TIMEZONE = ZoneInfo("Asia/Seoul")` 설정됨 |
+| **SQLAlchemy 모델** | ✅ 정상 | `server_default=func.now()` → DB 타임존(서울) 따름 |
+
+### 문제점
+- Python 코드에서 `datetime.now()` (naive) 또는 `datetime.now(timezone.utc)` (UTC) 혼용
+- 타임존이 적용된 현재 시간을 얻는 공통 유틸리티 없음
+
+---
+

+```python
+# Before
+from datetime import datetime, timezone
+
+user.last_login_at = datetime.now(timezone.utc)
+
+# After
+from app.utils.timezone import now
+
+user.last_login_at = now()

+# Before
+from datetime import datetime
+
+upload.uploaded_at = datetime.now()
+
+# After
+from app.utils.timezone import now

+

+from datetime import datetime
+
+today = datetime.today().strftime("%Y-%m-%d")
+
+# After
+from app.utils.timezone import today_str

+
+> **참고**: logger.py에서는 **날짜만 사용하는 것이 맞습니다.**
+> 로그 파일명이 `{날짜}_app.log`, `{날짜}_error.log` 형식이므로 일별 로그 파일 관리에 적합합니다.
+> 시간까지 포함하면 매 시간/분마다 새 파일이 생성되어 로그 관리가 어려워집니다.

+| 7 | Logger 유틸리티 수정 | `app/utils/logger.py` | ✅ 완료 |
+
+---
+
+## 예상 작업 범위
+
+- **신규 파일**: 1개 (`app/utils/timezone.py`)
+- **수정 파일**: 6개
+- **수정 위치**: 약 15곳
+
+---
+
+## 참고 사항
+
+### naive datetime vs aware datetime
+- **naive datetime**: 타임존 정보가 없는 datetime (예: `datetime.now()`)
+- **aware datetime**: 타임존 정보가 있는 datetime (예: `datetime.now(TIMEZONE)`)
+
+### 왜 서울 타임존을 사용하는가?
+1. 데이터베이스가 Asia/Seoul로 설정됨
+2. 서비스 대상 지역이 한국
+3. Python 코드와 DB 간 시간 일관성 확보
+
+### 주의사항
+- 기존 DB에 저장된 시간 데이터는 이미 서울 시간이므로 마이그레이션 불필요
+- JWT 토큰 만료 시간 비교 시 타임존 일관성 필수
+- 로그 파일명에 사용되는 날짜도 서울 기준으로 통일
