这个好像可以-

$ scala -cp joda-time-2.9.jar
Welcome to Scala 2.11.8 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_92).
Type in expressions for evaluation. Or try :help.

scala> import org.joda.time.DateTime

scala> import org.joda.time.format.DateTimeFormat

scala> val fmt2 = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ssZZ")
fmt2: org.joda.time.format.DateTimeFormatter = org.joda.time.format.DateTimeFormatter@12f40c25

scala> import org.joda.time.DateTimeZone
import org.joda.time.DateTimeZone

scala> val x = fmt2.parseDateTime("2016-04-26T21:00:00+00:00").withZone(DateTimeZone.UTC)
