What is Unix Timestamp?

Unix Timestamp is a way to represent time as the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC (Coordinated Universal Time). This representation is widely used in computer systems because it simplifies time to an integer, making it easy to store and compute.

Timestamp Units

• Seconds (s): The most common unit, typically 10 digits (e.g., 1622505600)
• Milliseconds (ms): One thousandth of a second, typically 13 digits (e.g., 1622505600000)
• Microseconds (μs): One millionth of a second, typically 16 digits
• Nanoseconds (ns): One billionth of a second, typically 19 digits

This tool primarily supports conversion of seconds and milliseconds timestamps.

Batch Conversion Tips

Although this tool is primarily designed for single conversions, you can achieve batch conversions through the following methods:

1. Prepare a text file containing multiple timestamps or datetimes
2. Enter one value per line
3. Copy each value into the conversion tool for conversion
4. Paste the results back into the file
