About Unix Timestamps

Unix timestamp (also known as Epoch time) is a system for describing points in time, defined as the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970.

Key Facts

Epoch Start: January 1, 1970, 00:00:00 UTC
Resolution: Typically measured in seconds, sometimes milliseconds
Range: Can represent dates from 1970 to 2038 (32-bit) or much further (64-bit)
Universal: Same value represents the same moment worldwide
Programming: Widely used in databases, APIs, and programming languages

Common Formats

Seconds: 1672531200 Standard Unix timestamp

Milliseconds: 1672531200000 JavaScript Date.now() format

ISO 8601: 2023-01-01T00:00:00.000Z International standard format

RFC 2822: Sun, 01 Jan 2023 00:00:00 GMT Email and HTTP headers format

Common Use Cases

Database Storage: Efficient storage of date/time data
API Responses: Standardized time representation in JSON
Log Files: Precise timing of events
Caching: Expiration times for cached data
Scheduling: Task scheduling and cron jobs
Analytics: Time-based data analysis

Timezone Considerations

Unix timestamps are always in UTC. When converting to human-readable formats, timezone offsets are applied for display purposes only. The underlying timestamp value remains the same regardless of the viewer's location.
