Frequently Asked Questions
Common questions about timestamp conversion
What is Unix timestamp?
Unix timestamp is the number of seconds elapsed from January 1, 1970 00:00:00 UTC (Unix epoch) to the specified time. It is an integer without timezone information and is widely used in programming and databases.
What is the difference between second-level and millisecond-level timestamps?
Second-level timestamp: 10 digits, precision in seconds, such as 1702099200. Commonly used in PHP, MySQL, etc. Millisecond-level timestamp: 13 digits, precision in milliseconds, such as 1702099200000. Commonly used in JavaScript, Java, etc.
Why is the conversion result 8 hours different from expected?
This is usually caused by timezone differences. This tool uses your local timezone (Beijing time UTC+8) for conversion. If the timestamp you see is from another timezone (such as UTC), you need to consider the time difference. The Beijing time of Unix epoch is 1970-01-01 08:00:00.
What is the Year 2038 problem?
The maximum value of a 32-bit signed integer is 2147483647, corresponding to 2038-01-19 03:14:07 UTC. Beyond this time, timestamps stored in 32-bit systems will overflow. Modern systems use 64-bit integers for storage, which can support billions of years later.
What date input formats are supported?
Supports multiple common formats: • 2023-12-09 12:00:00 • 2023/12/09 12:00:00 • Dec 09, 2023 12:00:00 • 2023-12-09 (defaults to 00:00:00 of that day)
