Get millisecond of LocalTime

November 13, 2021

I have a given LocalTime instance and I just need to get the millisecond value.

For example, to get the hour value I call myLocalTime.getHour(); and to get the minute value I call myLocalTime.getMinute();. But it seems like there is no function to get the millisecond… how do I get it?

>Solution :

Just use getNano() and then divide by a million (the number of nanoseconds in a millisecond). You can use TimeUnit to obtain that "a million" in a more programmatic way, or Duration:

Complete example:

import java.time.Duration;
import java.time.LocalTime;

public class Test {
    public static void main(String[] args) throws Exception {
        long nanosPerMillisecond = Duration.ofMillis(1).toNanos();
        
        LocalTime now = LocalTime.now();
        System.out.println(now);
        System.out.println(now.getNano() / nanosPerMillisecond);
    }
}

Sample output:
