![]() ![]() In this blog, we have seen different methods to create a date object and theĪssociated way to cast that object into an ISO 8601 date representation. Patterns for formatting and parsing are available in the Javadoc of ofPattern ( "yyyy-MM-dd'T'HH:mm:ss.SSSXXX" ). Use customized date-time pattern: // Conversion DateTimeFormatter. ![]() of ( "CET" )) // Conversion String text = DateTimeFormatter. Let’s see the code: // Input ZonedDateTime d = LocalDate. Means that January is equal to 1 instead of 0, so you can use the digit Then this object accepts a formatter toįormat the date representation in string. It uses a builder to construct theĭate time with time zone step-by-step. Solution among all the possibiliites here. ![]() The package java.time, formerly Joda-Time, provides the most elegant getTimeZone ( "CET" )) String text = sdf. getTime () // Conversion SimpleDateFormat sdf sdf = new SimpleDateFormat ( "yyyy-MM-dd'T'HH:mm:ss.SSSXXX" ) sdf. FEBRUARY, 16, 20, 22, 28 ) Date date = calendar. Input GregorianCalendar calendar calendar = new GregorianCalendar ( 2017, Calendar. format ( date ) // Output // "T20:22:28.000+01:00" įor gregorian calendar, we don’t need to set explicitly the millisecond datepart Such line will lead to an erroneous value for millisecond. Please be aware that setting the field of millisecond is necessary: lack of When using Calendar, we need to get an instance, then build a date object with currentTimeMillis ()) // Conversion SimpleDateFormat sdf sdf = new SimpleDateFormat ( "yyyy-MM-dd'T'HH:mm:ss.SSSXXX" ) sdf. You can see the difference in the following paragraphs. This is a little bit tricky because we’re using the current time, Just run above program as Java Application in Eclipse IDE and you are all set.Here’s an example to demonstrate how to convert a to ISO 8601ĭate string. LocalDateTime localDateTime = instant.atZone(defaultZoneId).toLocalDateTime() ZoneId defaultZoneId = ZoneId.systemDefault() Log("Current Time in Epoch: " + epochTime) ![]() getTime() returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object. parse() parses text from the beginning of the given string to produce a date.ĭate date = crunchifyFormat.parse(currentTime) String currentTime = crunchifyFormat.format(today) format() formats a Date into a date/time string. SimpleDateFormat crunchifyFormat = new SimpleDateFormat("MMM dd yyyy HH:mm:ss.SSS zzz") Constructs a SimpleDateFormat using the given pattern In this tutorial we will go over simple simple steps on how to convert current time to Epoch time.ĭate today = Calendar.getInstance().getTime() Wondering how to convert time to your user’s local time dynamically? Well, using Java’s getTime() returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object. Are you working on Java Enterprise project? What if your customers are located in different Geo location? It’s always good practice to show your users their local time on UI page. ![]()
