Supported formats:
- Timestamp: Unix timestamp in seconds (1640995200) or milliseconds (1640995200000)
- Date/Time: ISO format (2022-01-01T00:00:00Z), readable format (Jan 1, 2022), or any valid date string
Convert between Unix timestamps (seconds since January 1, 1970 UTC) and human-readable date formats including ISO 8601, UTC, and local time. Essential for developers working with APIs, databases, log files, and any system that uses Unix timestamps for time representation. Debug time zones, verify expiration times, and convert timestamps for display or storage.
What is Timestamp Converter?
A Unix timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix epoch). Timestamps provide a consistent, timezone-independent way to represent dates and times. Converting between timestamps and readable dates is essential for debugging, logging, API development, and displaying dates in applications.
Common Use Cases
- API development - convert timestamps from API responses to readable dates
- Database queries - convert timestamps for date-based queries and filtering
- Log analysis - convert timestamps in log files to readable timestamps
- Debugging - verify expiration times in tokens, cookies, and sessions
- Data analysis - convert timestamps for time-series analysis
- Display formatting - convert timestamps to user-friendly date formats
- Timezone debugging - understand how timestamps relate to different timezones
How It Works
The timestamp converter accepts Unix timestamps (in seconds or milliseconds) and converts them to various date formats including ISO 8601 (YYYY-MM-DDTHH:mm:ssZ), UTC, and local time. It also works in reverse, converting human-readable dates to Unix timestamps. The tool handles timezone conversions, supports both seconds and milliseconds precision, and provides multiple output formats for different use cases.
