About Unix Timestamps
What is Unix Time?
Unix timestamp (also called epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It's a standard way to represent time in computing systems.
Common Uses
- Databases: Storing timestamps efficiently
- APIs: Standard time format for data exchange
- Logging: Recording when events occurred
- Scheduling: Cron jobs and task scheduling
- Caching: Setting expiration times
Seconds vs Milliseconds
- Unix (seconds): Standard format, used by most systems
- JavaScript (milliseconds): 1000x larger, includes millisecond precision
- Conversion: Multiply by 1000 to go from seconds to milliseconds
Important Dates
- Unix Epoch: January 1, 1970, 00:00:00 UTC
- Y2K38: January 19, 2038 - 32-bit systems will overflow
- Negative values: Represent dates before 1970
Timezone Considerations
Unix timestamps are always in UTC. When converting to human-readable dates, the timezone determines how the date is displayed, not the underlying timestamp value.
