Joda DateTime to Unix DateTime
提问by アレックス
It's odd enough, but I didn't find any result about converting Joda(Time) DateTimeto Unix DateTime (or timestamp, whichever is the correct name). How can I do this?
这很奇怪，但我没有找到任何关于将 Joda(Time) 转换DateTime为 Unix DateTime（或时间戳，以正确的名称为准）的结果。我怎样才能做到这一点？

Any object that inherits from BaseDateTime(including DateTime) has the method
任何继承自BaseDateTime（包括DateTime）的对象都具有该方法
public long getMillis()
According to the APIit:
根据API它：
Gets the milliseconds of the datetime instant from the Java epoch of 1970-01-01T00:00:00Z.
从 Java 纪元 1970-01-01T00:00:00Z 获取日期时间瞬间的毫秒数。
So a working example to get the secondswould simply be:
因此，获取秒数的工作示例只是：
new DateTime().getMillis() / 1000
For completeness, the definition of the Unix Timestamp according to Wikipedia:
Unix time, or POSIX time, is a system for describing instants in time, defined as the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970, not counting leap seconds
Unix 时间或 POSIX 时间是一种用于描述瞬间的系统，定义为自 1970 年 1 月 1 日星期四 00:00:00 协调世界时 (UTC) 以来经过的秒数，不计算闰秒

Java 8 added a new API for working with dates and times. With Java 8 you can use
Java 8 添加了一个用于处理日期和时间的新 API。使用 Java 8，您可以使用
long unixTimestamp = Instant.now().getEpochSecond();
