timestamp converter

Timestamp Converter is a tool dedicated to converting 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

Cross-platform and compatibility: supports multiple operating systems and mobile terminals, some tools provide web versions without installation, and are compatible with mainstream programming languages (such as Python's datetime, JavaScript's Date.now()).

High precision and multiple formats: supports second to nanosecond level timestamp conversion, can handle decimal and hexadecimal input, and the output format can be customized (such as Chinese "September 25, 2025" or English "September 25, 2025").

Intelligent time zone processing: Automatically identify or manually set time zones (such as UTC, Beijing time UTC+8) to avoid the 1-second deviation caused by daylight saving time/leap seconds; supports batch conversion (such as CSV/Excel import and export) and timestamp addition and subtraction operations (such as "current timestamp + 86400 seconds").

Additional functional expansion: integrated code snippet generation, historical event correlation (such as "This timestamp corresponds to September 25, 2024"), API integration capabilities, and improved development efficiency.

Core functions

Two-way conversion:

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

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

Calculation and comparison: Supports timestamp addition and subtraction (such as "7 days later") and interval calculation (such as "how many days/hours the difference is"), suitable for task timeout judgment and scheduled task debugging.

Formatting and integration: Customize output formats (such as HH:mm:ss.SSS), language localization, support programming language code generation and HTTP API integration, and adapt to automated processes.

Batch processing: Convert multiple timestamps (such as log file lists) at one time, and combine CSV/Excel import and export to achieve data analysis.

FAQ

Inaccurate conversion results: When the time zone is not specified, the tool uses UTC time by default, and the user expects local time, or the wrong choice is made when manually setting the time zone, which will cause the converted time to be inconsistent with expectations, such as a difference of 8 hours.

Improper handling of daylight saving time: If the tool does not automatically handle daylight saving time, additional time differences need to be added and subtracted during manual conversion. For example, UTC-5 needs to be adjusted to UTC-4 for U.S. daylight saving time, otherwise time deviation will occur.
