包路径：java.time.Clock
类名称：Clock
方法名：systemDefaultZone

Clock.systemDefaultZone介绍

[英]Obtains a clock that returns the current instant using the best available system clock, converting to date and time using the default time-zone.

This clock is based on the best available system clock. This may use System#currentTimeMillis(), or a higher resolution clock if one is available.

Using this method hard codes a dependency to the default time-zone into your application. It is recommended to avoid this and use a specific time-zone whenever possible. The #systemUTC() should be used when you need the current instant without the date or time.

The returned implementation is immutable, thread-safe and Serializable. It is equivalent to system(ZoneId.systemDefault()).
[中]获取一个时钟，该时钟使用最佳可用系统时钟返回当前时刻，并使用默认时区转换为日期和时间。
此时钟基于最佳可用系统时钟。这可能使用System#currentTimeMillis（），或更高分辨率的时钟（如果有）。
使用此方法将对默认时区的依赖项硬编码到应用程序中。建议避免这种情况，并尽可能使用特定的时区。当您需要当前时刻而不需要日期或时间时，应使用#systemUTC（）。
返回的实现是不可变的、线程安全的和可序列化的。它相当于系统（ZoneId.systemDefault（））。
