How to convert UTC timestamp to device local time in android

Question

I need to convert the UTC time stamp that i get from the server to local device time. currently i get 5 hrs difference in my time. for example when i post to server the post time says 5 hours ago instead of a second ago. How to fix this issue. thanks

Below is the code that i do

long timestamp = cursor.getLong(columnIndex);             CharSequence relTime = DateUtils                     .getRelativeTimeSpanString(timestamp * 1000                             + TimeZone.getDefault().getRawOffset(),                             System.currentTimeMillis(),                             DateUtils.MINUTE_IN_MILLIS);             ((TextView) view).setText(relTime); 

Answer 1

Java:

int offset = TimeZone.getDefault().getRawOffset() + TimeZone.getDefault().getDSTSavings(); long now = System.currentTimeMillis() - offset; 

Kotlin:

val offset: Int = TimeZone.getDefault().rawOffset + TimeZone.getDefault().dstSavings val now: Long = System.currentTimeMillis() - offset

Converting a date String of the format "2011-06-23T15:11:32" to our time zone.

private String getDate(String ourDate) {     try     {         SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");         formatter.setTimeZone(TimeZone.getTimeZone("UTC"));         Date value = formatter.parse(ourDate);          SimpleDateFormat dateFormatter = new SimpleDateFormat("MM-dd-yyyy HH:mm"); //this format changeable         dateFormatter.setTimeZone(TimeZone.getDefault());         ourDate = dateFormatter.format(value);          //Log.d("ourDate", ourDate);     }     catch (Exception e)     {         ourDate = "00-00-0000 00:00";     }   return ourDate; }
