本文整理了Java中java.time.ZonedDateTime.now()方法的一些代码示例，展示了ZonedDateTime.now()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ZonedDateTime.now()方法的具体详情如下：
包路径：java.time.ZonedDateTime
类名称：ZonedDateTime
方法名：now

ZonedDateTime.now介绍

[英]Obtains the current date-time from the system clock in the default time-zone.

This will query the Clock#systemDefaultZone() in the default time-zone to obtain the current date-time. The zone and offset will be set based on the time-zone in the clock.

Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.
