包路径：org.threeten.bp.Instant
类名称：Instant
方法名：now

Instant.now介绍

[英]Obtains the current instant from the system clock.

This will query the Clock#systemUTC() to obtain the current instant.

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

  // Small negative delta is fine too, it would mean that the packet came from the future,
  // which can be explained by our clock being a little behind.
  // Huge negative delta is from previous mod32, and should be changed to small positive.
  // Huge positive delta might come from a packet a little from the future and next mod32,
  // we want instead a small negative delta.
