如何計算任意年份的起始時間戳
UTC 中任意年份的起點是 1 月 1 日 00:00:00 的 Unix 時間戳。由於各年長度不一(閏年多一天),最安全的做法是讓日期函式庫計算邊界,而不是在上一年的基礎上加固定秒數。
- JavaScript: Date.UTC(2026, 0, 1) / 1000 = 1767225600
- Python: int(datetime(2026, 1, 1, tzinfo=timezone.utc).timestamp())
- Linux: date -u -d '2026-01-01' +%s
- Start of 2025 in UTC: 1735689600
- Start of 2027 in UTC: 1798761600
