Why is getLocalMillis() of LocalTime in Joda Time is a protected method?
提问by Jedi Knight
I wanted to convert joda time LocalTime to millis or milliseconds. I saw that the getLocalMillis is a protected method. Looks like there is no method to get the millis value of LocalTime.
我想将 joda 时间 LocalTime 转换为毫秒或毫秒。我看到 getLocalMillis 是一种受保护的方法。看起来没有方法可以获取LocalTime的毫秒值。
So, do I have to get the values of each field in millis and then add them up to get the total millis ? Why does Joda Time not have a public method for getting Local Millis ?
那么，我是否必须以毫秒为单位获取每个字段的值，然后将它们相加以获得总毫秒数？为什么 Joda Time 没有获取 Local Millis 的公共方法？

A LocalTimedoes not represent an absolute instant in time, but rather it describes a time of any day for an arbitrary timezone.
ALocalTime不代表时间上的绝对瞬间，而是描述任意时区的任何一天的时间。
Render your LocalTimeinto an DateTimevia LocalTime#toDateTimeToday()or LocalTime#toDateTimeToday(DateTimeZone)if you're looking for the moment described by that time today. Or if you want that moment on another day, construct the appropriate LocalDateand see the LocalDate#toDateTime(...)methods. Then call DateTime#getMillis().
将您渲染LocalTime成一个DateTime通孔，LocalTime#toDateTimeToday()或者LocalTime#toDateTimeToday(DateTimeZone)如果您正在寻找今天那个时间所描述的时刻。或者，如果您希望在另一天的那一刻，构建适当的LocalDate并查看LocalDate#toDateTime(...)方法。然后调用DateTime#getMillis()。

You can use also .toDate().getTime()
你也可以使用 .toDate().getTime()

If you really need the time milliseconds, you can also do:
如果你真的需要时间毫秒，你也可以这样做：
LocalTime#get(DateTimeFieldType.millisOfDay())
