Unix Timestamp Guide
Learn Unix timestamp formats, epoch conversion steps, timezone behavior and common developer use cases.
Common timestamp converter uses
Logs and observability
Read timestamps from server logs, application events, analytics, telemetry, monitoring alerts, audit trails and incident timelines.
Databases and SQL
Check epoch fields used by PostgreSQL, MySQL, MariaDB, SQLite, SQL Server, BigQuery, Snowflake, Redis and document databases.
Programming languages
Verify time values from JavaScript, TypeScript, Python, Java, PHP, Go, Ruby, Rust, C#, C, C++, Kotlin and Swift applications.
Linux, DevOps and cloud
Inspect Unix shell output, file modification times, cron jobs, containers, CI/CD pipelines, cloud events and infrastructure automation.
Data and spreadsheets
Normalize dates for CSV files, Excel, Google Sheets, ETL jobs, data warehouses, reporting tools and analytics dashboards.
Security and authentication
Review token expiration, session lifetimes, signed requests, access logs, security events and time-based authorization rules.
Blockchain and distributed systems
Translate block times, transaction events, message queues, event streams and distributed-system records into readable dates.
Supported timestamp formats and conversions
| Format | Example | Use |
|---|---|---|
| Unix seconds | 1704067200 | Standard 10-digit epoch time used by Unix, Linux, APIs and databases. |
| Unix milliseconds | 1704067200000 | 13-digit timestamp used by JavaScript, Java and many event systems. |
| ISO 8601 / RFC 3339 | 2024-01-01T00:00:00Z | Portable date format for JSON, APIs, logs and data exchange. |
| Local date and time | 2024-01-01 02:00:00 | Wall-clock time interpreted in the timezone you select. |
| UTC, GMT and IANA zones | UTC · GMT+2 · Europe/Sofia | Fixed offsets or location-based timezone and DST rules. |
How to convert a timestamp or date
- Paste an epoch value, confirm seconds or milliseconds, and choose the output timezone.
- To convert the other way, enter a date and time and select the timezone in which it occurs.
- Copy epoch seconds, epoch milliseconds, the readable local date or the ISO 8601 value.
