The makers of Joda-Time have asked us to migrate to its replacement, the java. time framework as soon as is convenient. While Joda-Time continues to be actively supported, all future development will be done on the java. time classes and their extensions in the ThreeTen-Extra project. The java-time framework is defined by JSR and built into Java 8 and later. An Instant is a moment on the timeline in UTC with a resolution of nanoseconds. Its epoch is the first moment of in UTC.
Apply an offset-from-UTC ZoneOffset to get an OffsetDateTime. Better yet, if known, apply a time zone ZoneId to get a ZonedDateTime. It looks like your longs are seconds, and not milliseconds. Date constructor takes time as millis, so. Those are probably timestamps in seconds and not in milliseconds which is required for the java new Date long constructor. Just multiply them by and you should be allright. The long values, most likely, correspond to Epoch timestamps, and the values are:.
One can convert these long values to java. Date , taking into account the fact java. Date uses millisecs — as previously hinted, but with some flaw - like this:. Below are the results of displaying the converted long value to java.
Date without using and using the DateFormat:. toString returns "Thu Jan 15 CET ". Make sure that your values are not in this situation lower than New Date number returns a date that's number milliseconds after 1 Jan Odds are you date format isn't showing hours, minutes, and seconds for you to see that it's just a little bit after 1 Jan You need to parse the date according to the correct parsing routing.
I don't know what a is, but if it's seconds after 1 JAN , then multiply it to yield milliseconds. If it is not, then convert it in some manner to milliseconds after if you want to continue to use java.
Works for me. You probably want to multiplz it with , since what you get are the seconds from and you have to pass the milliseconds from jan 1 Date has constructor new Date Long milliseconds - Allocates a Date object and initializes it to represent the specified number of milliseconds since the standard base time known as "the epoch", namely January 1, , GMT.

tl;dr java. Internally, a count of nanoseconds since TZ. Know Your Data People use various precisions in tracking time as a number since an epoch.
So when you obtain some numbers to be interpreted as a count since an epoch, you must determine: What epoch? Many epochs dates have been used in various systems. But you should not assume this epoch. What precision?
Are we talking seconds, milliseconds , microseconds , or nanoseconds since the epoch? What time zone? But sometimes, when involving inexperienced or date-time ignorant programmers, there may be an implied time zone.
Lessons learned: Determine, don't assume, the meaning of received data. Read the doc. Your Data Your data seems to be in whole seconds. Joda-Time The java.

He edited it within 5 minute grace period. thanks for the clarification. That's the ownly downside SO has getInstance ; c. setTimeInMillis l ; System. Let us see the syntax of these different methods separately. Start Your Free Software Development Course. In Java, the timestamp is defined as the time and the date format that is displayed using timestamp class which is done using java. util class for using date and calendar class whereas there is java.
sql package for using timestamp class in java to implement timestamp in the java program. The conversion of the timestamp to date would result in displaying both date and time in milliseconds which is usually a human-readable format. Therefore exact working of the timestamp to date conversion is done using 3 different ways and is done using timestamp class using java. util or java. sql package. In Java, there is java.
Date class which is provided by the java. util package and we will be using the constructor of this class to convert timestamp to date. The working of this method of conversion is firstly it will obtain the value which is long value as a parameter from the Date class constructor where it results in timestamp object which will convert long value using getTime method. In the above example, we can see that we have first imported java. sql, Timestamp package, and java. Date package for using date constructor we need Date class and to use timestamp we use Timestamp class.
Then using println we will display the converted date from the obtained timestamp. The output of the above program is as shown in the above screenshot. This is another method of converting timestamp to date in Java using again the date class of java. date package. In this method, it just extends the date class where the timestamp instance is assigned to date directly and therefore the date object which results as output in the date format which was earlier in the timestamp.
Let us see an example below for demonstrating such method in java:. This can be seen in the above screenshot. Another method of converting timestamp to date in java is using calendar class which is rarely used by any developers. We can obtain calendar class by the java. Calendar package where we use this calendar class along with which we have to use getInstance function to get timestamp instance and getTime to get the date along with time which will be converted from the timestamp.
Let us see an example below:.
The following Java program is used to convert date from long to Date object and Date object to long. Long to Date Object,. Get the Date in long datatype and convert to Date object using the above code. Date object to long,. getTime ;. Create a Date object and get current date using Date. Convert the obtained date to long using getTime method.
