Timestamp Format Reference

Unix timestamp represents the number of seconds or milliseconds since January 1, 1970, 00:00:00 UTC. This online timestamp converter supports the following formats:

TypeDescriptionExample
Unix SecondsSeconds since 1970-01-01 00:00:00 UTC1609459200
Unix MillisecondsMilliseconds since 1970-01-01 00:00:00 UTC1609459200000
ISO 8601International standard date and time format2021-01-01T00:00:00Z

Code Examples for Getting Timestamps

Here are code examples for getting the current timestamp in various programming languages, helping developers correctly obtain Unix timestamps across different platforms:

About Timestamp Converter

What is a Timestamp?

A timestamp is an integer value representing the number of seconds or milliseconds elapsed since January 1, 1970, 00:00:00 UTC (Coordinated Universal Time). It's a universal standard for tracking time in computer systems, unaffected by factors like time zones or daylight saving time, making it convenient for representing specific moments globally. Unix timestamps are widely used in programming, database storage, log recording, and other scenarios, serving as an essential tool for programmers working with time.

When to Use a Timestamp Converter?

  • Converting timestamps in program logs to readable time formats
  • Developing or testing applications that handle Unix timestamps
  • Analyzing data files or logs containing timestamps
  • Converting specific date and time to timestamp format for API calls

Features

  • Support for bidirectional conversion between second/millisecond Unix timestamps and standard time formats
  • Real-time display of various timestamp formats for the current time
  • Support for multiple timezone settings to meet global user needs
  • Clean and intuitive interface for quick online timestamp conversion
