Support for what you want to do is built in to the latest JDKs with a little known class called TimeUnit. What you want to use is java.util.concurrent.TimeUnit to work with intervals. SimpleDateFormat does just what it sounds like it does, it formats instances of java.util.Date, or in your case it converts the long value … Read more
You can use new java.util.Date(Long.parseLong(timeInMillis)). With this Date object there are several ways to extract the date in your desired String format, the simplest way using Date.toString(). Alternatively, and more appropriately you can use a SimpleDateFormat with the exact pattern you want.
You can escape literals using single quotes. SimpleDateFormat formatter = new SimpleDateFormat(“EEE, d MMM yyyy ‘at’ hh:mma”); This will output Wed, 26 May 2010 at 11:17am
final Date currentTime = new Date(); final SimpleDateFormat sdf = new SimpleDateFormat(“EEE, MMM d, yyyy hh:mm:ss a z”); sdf.setTimeZone(TimeZone.getTimeZone(“UTC”)); System.out.println(“UTC time: ” + sdf.format(currentTime));
I don’t say it’s a nice solution, but it seems to be a way through. Map<Long, String> dayOfWeekTexts = Map.of(1L, “Mo”, 2L, “Di”, 3L, “Mi”, 4L, “Do”, 5L, “Fr”, 6L, “Sa”, 7L, “So”); Map<Long, String> monthTexts = Map.ofEntries(Map.entry(1L, “Jan”), Map.entry(2L, “Feb”), Map.entry(3L, “Mär”), Map.entry(4L, “Apr”), Map.entry(5L, “Mai”), Map.entry(6L, “Jun”), Map.entry(7L, “Jul”), Map.entry(8L, “Aug”), Map.entry(9L, “Sep”), … Read more
You are currently using the SimpleDateFormat(String) constructor. This implies the default locale and as the Locale documentation tells you, be wary of the default locale as unexpected output can be produced on various systems. You should instead use the SimpleDateFormat(String, Locale) constructor. It is going to take in an additional parameter – the locale you … Read more
JSR-310 has been delivered with Java 8 which provides enhanced support for parsing temporal values where components may now be optional. Not only can you make the zone optional, but you can also make the time component optional and return the correct temporal unit for the given string. Consider the following test cases. public class … Read more
Change HH to hh as long timeInMillis = System.currentTimeMillis(); Calendar cal1 = Calendar.getInstance(); cal1.setTimeInMillis(timeInMillis); SimpleDateFormat dateFormat = new SimpleDateFormat( “dd/MM/yyyy hh:mm:ss a”); dateforrow = dateFormat.format(cal1.getTime()); Note that dd/mm/yyyy – will give you minutes instead of the month.
The Android version of SimpleDateFormat doesn’t support the X pattern so XXX won’t work but instead you can use ZZZZZ which does the same and outputs the timezone in format +02:00 (or -02:00 depending on the local timezone).
All I needed was this : SimpleDateFormat sdf = new SimpleDateFormat(“yyyy.MM.dd HH:mm:ss”); sdf.setTimeZone(TimeZone.getTimeZone(“GMT”)); SimpleDateFormat sdfLocal = new SimpleDateFormat(“yyyy.MM.dd HH:mm:ss”); try { String d = sdf.format(new Date()); System.out.println(d); System.out.println(sdfLocal.parse(d)); } catch (Exception e) { e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates. } Output : slightly dubious, but I want … Read more
