What is Unix Timestamp?
Unix timestamp is an integer representing the number of seconds elapsed since January 1, 1970 00:00:00 UTC (the Unix Epoch).
Time Range
- Start time: January 1, 1970 00:00:00 UTC, timestamp: 0
- End time: January 19, 2038 03:14:07 UTC, timestamp: 2,147,483,647
* Note: This limitation is based on 32-bit systems. 64-bit systems can represent ±292,277,026,596 years.
Common Units
- Seconds: Most commonly used, 10 digits
- Milliseconds: 1/1000 of a second, 13 digits
- Microseconds: 1/1,000,000 of a second, 16 digits
- Nanoseconds: 1/1,000,000,000 of a second, 19 digits
Why Use Timestamps?
- Unified standard: Not affected by time zones
- Easy calculation: Can be directly compared
- Storage efficient: Represents complete date and time with a single number
- Cross-platform: Supported by all mainstream programming languages
Year 2038 Problem
On 32-bit systems, Unix timestamp will reach its maximum value of 2,147,483,647 on January 19, 2038 03:14:07 UTC, potentially causing overflow issues. Modern 64-bit systems are not affected by this limitation.
