For UTC time transfer to SG local time use:
public static final SimpleDateFormat SDF4_UTC = new SimpleDateFormat ("Yyyy-mm-dd HH:mm:ss. SSS ",
Locale.english);
public static final SimpleDateFormat SDF7_UTC = new SimpleDateFormat ("Yyyy-mm-dd HH:mm:ss",
Locale.english);
public static final SimpleDateFormat SDF13_UTC = new SimpleDateFormat ("hh:mm",
Locale.english);
public static int time_offset=0;
static{
Sdf4_utc.settimezone (Timezone.gettimezone ("Europe/london"));
Sdf7_utc.settimezone (Timezone.gettimezone ("Europe/london"));
Sdf13_utc.settimezone (Timezone.gettimezone ("Europe/london"));
TimeZone GMT = Timezone.gettimezone ("Europe/london");
Calendar gmtcal = Calendar.getinstance (GMT);
Time_offset = Gmtcal.get (Calendar.dst_offset);
LOG.D ("Gyy", "Time_offset" +time_offset);
}

String Datedisplay=constants.sdf5.format (Constants.sdf4.parse (medals.get (position). Getmedalupdatetime ()));
