First, we’ll try with the simple way to get the time in milliseconds format is from Date class. Date class has a method getTime()which returns the milliseconds in long value for the given time or current time. 01 02 03 04 05
I created an entity TrackPointCD, which has a date property. When reading an entity, I can't get a timestamp with milliseconds, I get only seconds without a fractional part. When creating an object, I see that the date has milliseconds: let point = TrackPointCD(context: context ) point...

In this tutorial we will see how to get current time or given time in milliseconds in Java. There are three ways to get time in milliseconds in java. 1) Using public long getTime() method of Date class. 2) Using public long getTimeInMillis() method of Ca
"getTimeInMillis() ... Returns: the current time as UTC milliseconds from the epoch." fromhttp://java.sun.com/j2se/1.5.0/docs/api/java/util/Calendar.html#getTimeInMillis 所谓的 epoch 就是 1970-01-01 00:00:00.000 这个时刻(不知道背后还有什么故事没有,欢迎知情者分享)。
The method returns the current time as UTC milliseconds.ExceptionNAGetting Time in Milliseconds from a Current Dated Calendar Instance ExampleThe following example shows the usage of Java Calendar getTimeInMillis() method.
