Do you mean?
long millis = System.currentTimeMillis() % 1000;
BTW Windows doesn't allow timetravel to 1969
C:\> date
Enter the new date: (dd-mm-yy) 2/8/1969
The system cannot accept the date entered.

Use Calendar
Calendar.getInstance().get(Calendar.MILLISECOND);
or
Calendar c=Calendar.getInstance();
c.setTime(new Date()); /* whatever*/
//c.setTimeZone(...); if necessary
c.get(Calendar.MILLISECOND);
In practise though I think it will nearly always equal System.currentTimeMillis()%1000; unless someone has leap-milliseconds or some calendar is defined with an epoch not on a second-boundary.

Java System currentTimeMillis() Method
Once loop is completed, we've again noted down the end time by getting the current time in milliseconds. package com.tutorialspoint; public class SystemDemo { public static void main(String[] args) throws InterruptedException { // start time of the code snippet long startTime = System.currentTimeMillis(); int sum = 0; // a time consuming task for (int i = 0; i < 10; i++) { // sleep for 100 ms Thread.sleep(100); sum += i; } // end time of the code snippet long endTime = System.currentTimeMillis(); System.out.println("Program took " + (endTime - startTime) + " ms") ; } }

Java: Get Current Time in Milliseconds — javaspring.net
In this example, we record the start time and end time using System.currentTimeMillis(), and then calculate the difference to get the execution time of the loop. When logging events in an application, it is often useful to include a timestamp. We can use the current time in milliseconds for this purpose. import java.util.logging.Level; import java.util.logging.Logger; public class LoggingWithTimestamp { private static final Logger LOGGER = Logger.getLogger(LoggingWithTimestamp.class.getName()); public static void main(String[] args) { long currentTime = System.currentTimeMillis(); LOGGER.log(Level.INFO, "[" + currentTime + "] This is a log entry."); } }

tl;dr
Duration.between( todayStart , now ).toMillis()
Details
Get the current moment in the wall-clock time used by the people of a certain region (a time zone).
ZoneId z = ZoneId.of( “Africa/Tunis” ) ;
ZonedDateTime now = ZonedDateTime.now( z ) ;
Get the first moment of the day. Do not assume this is 00:00:00. Let java.time determine.
ZonedDateTime todayStart = now.toLocalDate().atStartOfDay( z ) ;
Represent the delta between them, the span of time unattached to the timeline, as a Duration.
Duration d = Duration.between( todayStart , now ) ;
A Duration has a resolution of nanoseconds. That is finer than the milliseconds you desire. A convenience method will ignore any microseconds or nanoseconds for you.
long millisSinceStartOfToday = d.toMillis() ;
About java.time
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.
Where to obtain the java.time classes?
- Java SE 8, Java SE 9, and later
- Built-in.
- Part of the standard Java API with a bundled implementation.
- Java 9 adds some minor features and fixes.
- Java SE 6 and Java SE 7
- Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
- Android
- Later versions of Android bundle implementations of the java.time classes.
- For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Use the LocalTime class:
long millis = LocalTime.now().toNanoOfDay() / 1_000_000;
Basil Bourque correctly points out that it isn’t always this simple: a Daylight Saving Time change (such as will occur in most of the US this Sunday) can mean that, for example, there may not be eight hours between midnight and 8 AM.
You can account for this by using a ZonedDateTime, which accounts for all calendar information, including DST changeovers:
ZonedDateTime now = ZonedDateTime.now();
ZonedDateTime start = now.truncatedTo(ChronoUnit.DAYS);
long millis = ChronoUnit.MILLIS.between(start, now);
