Time libraries in Scala
Scala has no default way to deal with dates and times. We have a few options. java.util.Date and java.util.Calendar These come included with java, so they may do if you don't need to do much and don't want to add any dependencies. But they're horrible and it's best not to use them. Joda-Time http://www.joda.org/joda-time/ The de facto standard date and time library for Java. nscala-time https://github.com/nscala-time/nscala-time A thin scala layer around Joda-Time. This adds some implicit conversions to make it easier to use, like the + and < operators.
import com.github.nscala_time.time.Imports._
DateTime.now + 2.months // returns org.joda.time.DateTime
Java 8 https://docs.oracle.com/javase/8/docs/api/java/time/package-summary.html If you use java 8 it's best to use the improved java.time.
