What is Unix Timestamp?
Unix Timestamp is the total number of seconds elapsed since 00:00:00 UTC on January 1, 1970 (not counting leap seconds).
Timestamp Format
- Second-level Timestamp: 10-digit number, accurate to seconds, e.g., 1704067200
- Millisecond-level Timestamp: 13-digit number, accurate to milliseconds, e.g., 1704067200000
Use Cases
- Database time field storage
- API interface time parameters
- Log time recording
- Scheduled task scheduling
- Cross-timezone time handling
Notes
- Timestamp is UTC time, needs to be converted to local time based on timezone
- Different programming languages may use second-level or millisecond-level timestamps
- JavaScript uses milliseconds, Java/Python typically use seconds
- 2038 Problem: Maximum timestamp for 32-bit systems is 2147483647 (January 19, 2038)
