How to convert Unix timestamp to Datetime in Scala

🎈 🎈 🎈


    import java.time.{Instant, LocalDateTime, ZoneId}

    val unixTimestamp: Long = 1714412428L
    val dateTime: LocalDateTime = LocalDateTime.ofInstant(Instant.ofEpochSecond(unixTimestamp), ZoneId.systemDefault())
    
    println(s"Converted Date: $dateTime")

Output:

Converted Date: 2024-04-29 17:40:28

Example only. There may be multiple ways to perform this operation.

Code Explanation

In this Scala example, the Unix timestamp 1714412428L is converted into a human-readable date using the Instant.ofEpochSecond() method to create an Instant object that corresponds to the specific moment in time represented by the Unix timestamp.
Then, we convert this Instant to a LocalDateTime object using LocalDateTime.ofInstant(), adjusting for the system's default time zone with ZoneId.systemDefault(). The result is a LocalDateTime object that represents the date and time 2024-04-29 17:40:28 in the local time zone, which is then printed in a human-readable format.
