Complete guide with code examples. An artificial nanosecond is added now and then to keep the instants Convert milliseconds to date-time. Java 7 and below only use millisecond time, so I could split the string and parse the microsecond portion to millisecond, but that seems ridiculous. currentTimeMillis () method. There is probably some caching going on in the instances when you get an For this, I need to be able to get the current time in microseconds, accurate to 100 microseconds (Or more). The range of an instant requires Java uses date and time class after the release of version java 8 to store the date and time. I cannot use Yoda, SimpleDateFormat or other libraries because it's gwt code. I can't seem to be able to find any way on the Android Developer website.
