Kotlin convert TimeStamp to DateTime

Question

I'm trying to find out how I can convert timestamp to datetime in Kotlin, this is very simple in Java but I cant find any equivalent of it in Kotlin.

For example: epoch timestamp (seconds since 1970-01-01) 1510500494 ==> DateTime object 2017-11-12 18:28:14.

Is there any solution for this in Kotlin or do I have to use Java syntax in Kotlin? Please give me a simple sample to show how I can resolve this problem. Thanks in advance.

Answer 1

private fun getDateTime(s: String): String? {     try {         val sdf = SimpleDateFormat("MM/dd/yyyy")         val netDate = Date(Long.parseLong(s) * 1000)         return sdf.format(netDate)     } catch (e: Exception) {         return e.toString()     } } 

Answer 2

Although it's Kotlin, you still have to use the Java API. An example for Java 8+ APIs converting the value 1510500494 which you mentioned in the question comments:

import java.time.*  val dt = Instant.ofEpochSecond(1510500494)                 .atZone(ZoneId.systemDefault())                 .toLocalDateTime()
