Android Format date with time zone

Question

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:m

Answer 1

If you want the date for a different timeZone (which the title suggests)

  val nowMillsUTC = System.currentTimeMillis()

  val timeZoneID = "Australia/Perth"
  val tz = TimeZone.getTimeZone(timeZoneID)

  val simpleDateFormat = SimpleDateFormat("HH.mm  dd.MMM.yyyy", Locale.getDefault())
  simpleDateFormat.setTimeZone(tz)
  val resultTxt = simpleDateFormat.format(nowMillsUTC)

  print(timeZoneID + " -> " + resultTxt)
  //   Australia/Perth -> 19.59  21.Mar.2019
