Unix Timestamp Converter Description
Convert Unix timestamps to readable dates and vice versa. Support for seconds (s), milliseconds (ms), microseconds (μs), and nanoseconds (ns).
How to use
- Timestamp to Date: Enter a Unix timestamp (e.g.,
1710500000). The tool automatically identifies the precision (s, ms, us, ns) based on the input length. - Date to Timestamp: Enter a date string (e.g.,
2024-03-15 14:30:00). The tool will generate the corresponding Unix timestamps in all precisions. - Quick Actions: Use buttons like 'Today 00:00' or 'Now' to quickly set common time points.
Core Definitions
- Unix Timestamp: The number of seconds (or milliseconds/microseconds/nanoseconds) that have elapsed since the Unix epoch (January 1st, 1970, at 00:00:00 UTC).
- Precision: High-frequency systems often use milliseconds (13 digits) or nanoseconds (19 digits) for logging and distributed tracing.
Cultural Date Formats
Date formatting varies globally. We provide the three most common structures:
- ISO (Y-M-D): Used internationally and common in East Asia.
- US (M/D/Y): Standard in the United States.
- European (D/M/Y): Widely used in Europe, South America, and parts of Asia.
Technical Implementation
This tool is built using React and the dayjs library for high-performance and accurate time manipulation. It handles local browser timezones and UTC offsets seamlessly.
The Year 2038 Problem (Y2K38)
32-bit Unix systems store time as a signed 32-bit integer. On January 19, 2038, these systems will overflow and fail to correctly represent time. This tool supports 64-bit precision to visualize dates far beyond 2038.
