我想将Joda Time UTC DateTime对象转换为本地时间。
这是一种艰苦的方法,它似乎有效。但必须有更好的方法。
这是没有声明声明的代码(在Scala中):
val dtUTC = new DateTime("2010-10-28T04:00")
println("dtUTC = " + dtUTC)
val dtLocal = timestampLocal(dtUTC)
println("local = " + dtLocal)
def timestampLocal(dtUTC: DateTime): String = {
// This is a laborious way to convert from UTC to local. There must be a better way.
val instantUTC = dtUTC.getMillis
val localDateTimeZone = DateTimeZone.getDefault
val instantLocal = localDateTimeZone.convertUTCToLocal(instantUTC)
val dtLocal = new DateTime(instantLocal)
dtLocal.toString
}
这是输出:
dtUTC = 2010-10-28T04:00:00.000 + 11:00 local = 2010-10-28T15:00:00.000 + 11:00
答案 0 :(得分:8)
这是我在当前项目中使用的内容。
val marketCentreTime = timeInAnotherTimezone.withZone(DateTimeZone.forID("Australia/Melbourne"))
这有帮助吗?
编辑:
这是在当前的TZ中花费一些时间并转换为布里斯班时间的东西。你可以使用相同的原则。
