![]() One limitation is that Unix time does not account for leap seconds, which are added to UTC to keep it in sync with the Earth’s rotation. While Unix time is a useful way to measure time, it is not a perfect representation of time or UTC. This number can represent any moment in time, both past and future, relative to the Unix epoch.įor example, the Unix time corresponding to the date and time “, 11:57:21 PM” would be 1680892041, which is calculated as the number of seconds between the Unix epoch and the specified date and time. The Unix time is a single number, increasing by one every second. It provides a simple and consistent way to represent time across different platforms and programming languages. Unix time is widely used in Unix-like operating systems and many other file formats and software applications. ![]() Unix time, also known as POSIX time or Epoch time, is a system for measuring time by counting the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC) on January 1, 1970. The below table presents various programming languages and their corresponding code snippets that demonstrate how to parse a date in human-readable format to a Unix timestamp in either milliseconds or seconds. String date = dateFormat.format(currentDate) ĭate +"%Y-%m-%d %H:%M:%S" -d timestamp = 1680811547 ĭateTime dateTime = DateTimeOffset.FromUnixTimeSeconds(timestamp).ToLocalTime().DateTime SimpleDateFormat dateFormat = new SimpleDateFormat("YYYY-MM-dd HH:mm:ss") LanguageĬode to Convert Timestamp to Human-Readable Date The below table presents various programming languages and their corresponding code snippets that demonstrate how to convert timestamps (in either milliseconds or seconds) to a human-readable date format. The following examples demonstrate how to get the current date and time in different programming language: Programming Language Long ts = System.currentTimeMillis()/1000 The following examples demonstrate how to get the current Unix timestamp in seconds, although some programming languages may return timestamps in milliseconds: Programming Language Current timestamp in various programming languages
