As Jon Skeet already said  java util Date does not have a time zone  A Date object represents a number of milliseconds since January 1  1970  12 00 AM  UTC  It does not contain time zone information   When you format a Date object into a string  for example by using SimpleDateFormat  then you can set the time zone on the DateFormat object to let it know in which time zone you want to display the date and time   Date date   new Date    DateFormat df   new SimpleDateFormat  yyyy-MM-dd HH mm ss        Use Madrid s time zone to format the date in df setTimeZone TimeZone getTimeZone  Europe Madrid      System out println  Date and time in Madrid      df format date      If you want the local time zone of the computer that your program is running on  use   df setTimeZone TimeZone getDefault

Date is always UTC-based    or time-zone neutral  depending on how you want to view it  A Date only represents a point in time  it is independent of time zone  just a number of milliseconds since the Unix epoch  There s no notion of a  local instance of Date   Use Date in conjunction with Calendar and or TimeZone getDefault   to use a  local  time zone  Use TimeZone getTimeZone  Europe Madrid   to get the Madrid time zone       or use Joda Time  which tends to make the whole thing clearer  IMO  In Joda Time you d use a DateTime value  which is an instant in time in a particular calendar system and time zone   In Java 8 you d use java time ZonedDateTime  which is the Java 8 equivalent of Joda Time s DateTime
