Have you tried to use TimeZone getDefault        Most applications will use TimeZone getDefault   which returns a TimeZone based   on the time zone where the program is running    Ref   http   developer android com reference java util TimeZone html

TimeZone tz   TimeZone getDefault    System out println  quot TimeZone    quot  tz getDisplayName false  TimeZone SHORT   quot  Timezone id     quot   tz getID      Output   TimeZone   GMT 09 30   Timezone id    Australia Darwin

All the answers here seem to suggest setting the daylite parameter to false  This is incorrect for many timezones which change abbreviated names depending on the time of the year  e g  EST vs EDT     The solution below will give you the correct abbreviation according to the current date for the timezone   val tz   TimeZone getDefault   val isDaylite   tz inDaylightTime Date    val timezone   tz getDisplayName isDaylite  TimeZone SHORT

I needed the offset that not only included day light savings time but as a numerial  Here is the code that I used in case someone is looking for an example   I get a response of  3 5   3 30   which is what I would expect in Tehran   Iran in winter and  4 5   4 30   for summer    I also needed it as a string so I could post it to a server so you may not need the last line   for getting currect time zone    TimeZone tz   TimeZone getDefault    Date now   new Date      Import part   x 0 for double number double offsetFromUtc   tz getOffset now getTime      3600000 0  String m2tTimeZoneIs   Double parseDouble offsetFromUtc
