timestamp converter

Timestamp Converter is a tool specifically designed to process the conversion between Unix timestamps (Epoch Time) and human-readable date and time formats. It supports high-precision conversion of seconds, milliseconds, microseconds, and nanoseconds. It can handle decimal/hexadecimal timestamp input and output custom formats (such as YYYY-MM-DD HH:mm:ss) or standard formats (ISO 8601, RFC 2822).

Software features

High precision and multi-format support

Supports second to nanosecond level timestamp conversion, and can handle decimal and hexadecimal input (such as 0x65A4BC40 converted to decimal 1705030400).

The output format can be customized (such as Chinese "September 25, 2025" or English "September 25, 2025"), or converted to a standard format.

Intelligent time zone processing

Automatically identify or manually set the time zone (such as UTC, Beijing time UTC+8) to avoid the 1-second deviation caused by daylight saving time/leap seconds.

For example: when converting UTC timestamps to Eastern Time, the tool automatically handles daylight saving time adjustments (for example, UTC-5 needs to be adjusted to UTC-4 for U.S. Daylight Savings Time).

Batch processing and extended functions

Supports CSV/Excel import and export, and can convert multiple timestamps (such as log file list) at one time.

Additional features include code snippet generation (Python/JavaScript), historical event correlation (such as "This timestamp corresponds to September 25, 2024"), API integration, etc.

Core functions

bidirectional conversion

Convert timestamp to date and time: input 1727228940 (second level), output 2024-09-25 14:29:00 (UTC+8); supports millisecond/microsecond level precision.

Convert date and time to timestamp: input 2024-09-25 14:29:00 (Beijing time), output 1727228940 (second level) or 1727228940000 (millisecond level).

Calculate and compare

Supports timestamp addition and subtraction (such as "current timestamp + 86400 seconds") and interval calculation (such as "how many days/hours the difference is"), which is suitable for task timeout judgment and scheduled task debugging.

Formatting and Integration

Customized output format (such as HH:mm:ss.SSS), language localization (switching between Chinese and English).

Generate programming language code snippets (such as Python's import time; print(int(time.time()))) or provide HTTP API to adapt to the automated process.

Batch processing

Combined with CSV/Excel import and export to achieve data analysis (such as batch conversion of timestamps in logs).

FAQ

Daylight saving time is not handled properly

Reason: The tool does not automatically adjust for daylight saving time, so you need to manually add or subtract the time difference.

Solution: Use a tool that supports automatic daylight saving time adjustment (such as TimeStamp Converter), or process it through code (such as JavaScript's Date object to automatically recognize daylight saving time).
