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.
