目前 Unix 紀元時間
Unix → 人類可讀
自動偵測秒、毫秒、微秒或奈秒
輸入 Unix 時間戳以查看可讀日期
人類可讀 → Unix
選擇日期以轉換為 Unix 時間戳

Technical Details
Edge Cases & Tricky Inputs
- •Timestamps before 1970-01-01 (negative values) are supported and converted correctly.
- •Millisecond timestamps (13 digits) are auto-detected and handled differently from second timestamps (10 digits).
- •Year 2038 problem: 32-bit systems overflow at 2147483647 — this tool uses 64-bit and handles dates far beyond 2038.
Performance & Processing
- •Conversion uses JavaScript's native Date object — results are identical to browser's date handling.
- •Timezone offset calculations respect the user's system locale settings.
Developer Notes
- •Unix epoch is defined as 1970-01-01T00:00:00Z (midnight UTC on January 1, 1970).
- •The tool displays both local time and UTC for every conversion.
Known Limitations
- •Dates before year 0001 or after year 9999 are outside the representable range.
- •Leap seconds are not accounted for (consistent with JavaScript Date behavior).
