scala 日期处理

For processing dates, the Java Joda Time project is popular and well documented. A project named 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.DateTimeDateTime. now + 2. monthsDateTime. nextMonth < DateTime. now + 2. months(2. hours + 45. minutes + 10. seconds). millis
