scala处理日期

https://github.com/nscala-time/nscala-time

For processing dates, the Java Joda Time project is popular and well documented. A project named nscala-time implements a Scala wrapper around Joda Time, and lets you write date expressions in a more Scala-like way, including these examples:

DateTime. now // returns org.joda.time.DateTime

DateTime. now + 2. months

DateTime. nextMonth   DateTime. now + 2. months

(2. hours + 45. minutes + 10. seconds). millis

    println(DateTime.nextMonth   DateTime.now + 2.months) // returns Boolean = true

    println(DateTime.now to DateTime.tomorrow) // return org.joda.time.Interval =   2009-04-27T13:47:14.840/2009-04-28T13:47:14.840

    println((DateTime.now to DateTime.nextSecond).millis) // returns Long = 1000

    println((2.hours + 45.minutes + 10.seconds))

    // returns com.github.nscala_time.time.DurationBuilder

    // (can be used as a Duration or as a Period)

    println((2.hours + 45.minutes + 10.seconds).millis)

    // returns Long = 9910000

    println(2.months + 3.days)

    // returns Period
