What is This Tool?
A Unix timestamp converter converts between Unix epoch timestamps and human-readable dates. Convert milliseconds or seconds since January 1, 1970 UTC to formatted dates, and vice versa. Essential for debugging logs, APIs, and database records that store time as integers.
Unix time (POSIX time) counts seconds since the epoch (1970-01-01T00:00:00Z). It is timezone-independent, compact, and universally sortable. JavaScript uses milliseconds; most backends use seconds. The Year 2038 problem affects 32-bit systems that overflow at 2,147,483,647 seconds.
Common Use Cases
Log Analysis
Convert Unix timestamps in server logs, error reports, and monitoring data to readable dates for debugging.
API Development
Debug created_at, updated_at, and expires_at timestamp fields in REST and GraphQL API responses.
Database Queries
Convert between human dates and epoch timestamps for filtering database records stored as integer timestamps.
JWT Expiration
Inspect exp (expiration) and iat (issued at) claims in JWT tokens, which use Unix timestamp seconds.
Frequently Asked Questions
Is Unix time in seconds or milliseconds?
Traditional Unix time is in seconds. JavaScript Date.now() returns milliseconds. This tool supports both and auto-detects based on magnitude.
Does Unix time account for time zones?
No. Unix time is always UTC. The displayed local time depends on your timezone setting, but the timestamp value itself is timezone-independent.
What is the Year 2038 problem?
Signed 32-bit integers overflow on January 19, 2038. Systems using 64-bit timestamps (most modern systems) are unaffected.
