|Kotlin 1.3 Adds Duration And Time API|

The latest release of Kotlin, the open source language originated by JetBrains as "a better Java", is available with a new Duration and Time Measurement API, as well as an improved Java-to-Kotlin converter.
Kotlin has achieved prominence and popularity thanks to Google promoting it as a first class language for Android to replace or supplement Java, making it the lead language for Android development back in 2017. Kotlin makes Android programming easier by reducing the need for long chunks of boilerplate code that the average programmer just doesn't get, or perhaps more accurately doesn't bother understanding at a deep level.
This latest update brings in a beta of the new Duration and Time Measurement API. This lets you measure durations in a variety of units including seconds, milliseconds, and nanoseconds. The developers hope that having a regular class to store duration will avoid errors caused by data being passed in the wrong unit. If the API expects the duration stored as primitive value like
The second improvement available in preview is an improved Java-to-Kotlin converter designed to minimize the amount of “red code” that has to be fixed manually after the conversion. The current converter almost always generates non-nullable types, which can lead to runtime errors from nullability mismatch later. The new version of the Java-to-Kotlin converter tries to infer nullability more correctly based on the Java type usages in the code, as well as fixing many other known bugs, such as incorrect handling of implicit Java type casts.
Other improvements include experimental generation of external declarations for npm dependencies in Gradle Kotlin/JS projects; a separate plugin for debugging Kotlin/Native code in IntelliJ IDEA Ultimate; and Java compilation support in multiplatform projects.
