how to change time format in android programmatically

I need to format the date into a specific string.

I used SimpleDateFormat class to format the date using the pattern "yyyy-MM-dd'T'HH:mm:ssZ" it returns current date as "2013-01-04T15:51:45+0530" but I need as "2013-01-04T15:51:45+05:30".

Below is the coding used,

Calendar c = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ", Locale.ENGLISH);      
Log.e(C.TAG, "formatted string: "+sdf.format(c.getTime()));

Output: formatted string: 2013-01-04T15:51:45+0530

I need the format as 2013-01-04T15:51:45+05:30 just adding the colon in between gmt time.

Because I'm working on Google calendar to insert an event, it accepts only the required format which I have mentioned.

You can use Joda Time instead. Its DateTimeFormat has a ZZ format attribute which does what you want.

Big advantage: unlike SimpleDateFormat, DateTimeFormatter is thread safe. Usage:

DateTimeFormatter fmt = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ssZZ")
    .withLocale(Locale.ENGLISH);

SimpleDateFormat, To understand the concept, let us consider the below scenarios where we get the time stamp from the server in GMT format (assuming), then we� This example demonstrates how do I format date and time in android.

You can also use "ZZZZZ" instead of "Z" in your pattern (according to documentation). Something like this

    Calendar c = Calendar.getInstance();
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZZZZZ", Locale.ENGLISH);      
    Log.e(C.TAG, "formatted string: "+sdf.format(c.getTime()));

Converting Date/Time Considering Time Zone — Android, In this tutorials, We explain How to Format DateTime in Android using SimpleDateFormat. Example Include These days most of the project required date and time formatting in Android. So we are setTimeZone(TimeZone. Android 10 deprecates the APK-based time zone data update mechanism (available in Android 8.1 and Android 9) and replaces it with an APEX-based module update mechanism.

Why not just do it manually with regexp?

String oldDate = "2013-01-04T15:51:45+0530";
String newDate = oldDate.replaceAll("(\\+\\d\\d)(\\d\\d)", "$1:$2");

Same result, with substring (if performance is an issue).

String oldDate = "2013-01-04T15:51:45+0530";
int length = oldDate.length();
String newDate = oldDate.substring(0, length - 2) + ':' + oldDate.substring(length - 2);

Comments
  • I don't think you can with a simpledateformat. So you will need to insert the : manually. Java 7 has introduced the X marker that has more formatting options than Z but it is not available on android (yet?).
  • If formatting manually is the task to be done(in reference to the above comment), you can search for the last + and then add a : after 2 indices.
  • @KazekageGaara It could also be a -...
  • While in 2013 it was reasonable to use Calendar and SimpleDateFormat, don’t do that anymore. Those classes are poorly designed and now long outdated, the latter in particular notoriously troublesome. Instead use OffsetDateTime and DateTimeFormatter, both from java.time, the modern Java date and time API. Or just OffsetDateTime.toString and no formatter.
  • I found a slightly different way of doing this, given the: DateTime my_date = new DateTime(); ... Set the date to something my_date = ... Then format it with: String curr_date = my_date.toLocalDate().toString("yyyy-MM-dd");
  • This is correct answer, @fargath you should mark it up.
  • This should be the correct answer. I find it ridiculous when people refer to libraries as a primary solution instead of it being a secondary suggestion. It's like threading cloth with a sword.
  • The documentation says it supports X.
  • For me this doesn't work. I get this string: 2018-07-06T11:46:43+0200. The colon in the timezone is missing. So it's not ISO8601.
  • I fail to see the linked documentation mentioning the possibility of 5 Z (ZZZZZ). Is that just me? Also on my Java 8 I get formatted string: 2019-03-21T16:06:30+0100 without colon, but the outcome on Android may be different.
  • Apart from SimpleDateFormat and TimeZone being poorly designed and long outdated: On my Java 8 TimeZone.getAvailableIDs()[358] is Australia/Yancowinna, and who knows what it will be in future Java versions? I wouldn’t be too sure about Android either, but haven’t tried.
  • you are right - the getAvailableID's is unreliable. I edited accordingly
