Examples with SimpleTimeZone java.util.SimpleTimeZone used on opensource projects

Example 26 with SimpleTimeZone

use of java.util.SimpleTimeZone in project joda-time by JodaOrg.

the class TestLocalDate_Basics method testToDate_autumnDST.

public void testToDate_autumnDST() {
    LocalDate base = new LocalDate(2007, 10, 2);
    SimpleTimeZone testZone = new SimpleTimeZone(3600000, "NoMidnight", Calendar.APRIL, 2, 0, 0, Calendar.OCTOBER, 2, 0, 3600000);
    TimeZone currentZone = TimeZone.getDefault();
    try {
        TimeZone.setDefault(testZone);
        Date test = base.toDate();
        check(base, 2007, 10, 2);
        assertEquals("Tue Oct 02 00:00:00 GMT+02:00 2007", test.toString());
    } finally {
        TimeZone.setDefault(currentZone);
    }
}

Example 27 with SimpleTimeZone

use of java.util.SimpleTimeZone in project pdfbox by apache.

the class DateConverter method formatTZoffset.

/*
     * Formats a time zone offset as #hh^mm
     * where # is + or -, hh is hours, ^ is a separator, and mm is minutes.
     * Any separator may be specified by the second argument;
     * the usual values are ":" (ISO 8601), "" (RFC 822), and "'" (PDF).
     * The returned value is constrained to the range -11:59 ... 11:59.
     * For offset of 0 millis, the String returned is "+00^00", never "Z".
     * To get a "general" offset in form GMT#hh:mm, write
     *      "GMT"+DateConverter.formatTZoffset(offset, ":");
     *
     * Take thought in choosing the source for the millis value. 
     * It can come from calendarValue.getTimeZone() or from 
     * calendarValue.get(Calendar.ZONE_OFFSET).  If a TimeZone was created
     * from a valid time zone ID, then it may have a daylight savings rule.
     * (As of July 4, 2013, the data base at http://www.iana.org/time-zones 
     * recognized 629 time zone regions. But a TimeZone created as 
     *      new SimpleTimeZone(millisOffset, "ID"), 
     * will not have a daylight savings rule. (Not even if there is a
     * known time zone with the given ID. To get the TimeZone named "xDT"
     * with its DST rule, use an ID of EST5EDT, CST6CDT, MST7MDT, or PST8PDT.
     *
     * When parsing PDF dates, the incoming values DOES NOT have a TIMEZONE value.
     * At most it has an OFFSET value like -04'00'. It is generally impossible to 
     * determine what TIMEZONE corresponds to a given OFFSET. If the date is
     * in the summer when daylight savings is in effect, an offset of -0400
     * might correspond to any one of the 38 regions (of 53) with standard time 
     * offset -0400 and no daylight saving. Or it might correspond to 
     * any one of the 31 regions (out of 43) that observe daylight savings 
     * and have standard time offset of -0500.
     *
     * If a Calendar has not been assigned a TimeZone with setTimeZone(), 
     * it will have by default the local TIMEZONE, not just the OFFSET.  In the
     * USA, this TimeZone will have a daylight savings rule.
     *
     * The offset assigned with calVal.set(Calendar.ZONE_OFFSET) differs
     * from the offset in the TimeZone set by Calendar.setTimeZone(). Example:
     * Suppose my local TimeZone is America/New_York. It has an offset of -05'00'.
     * And suppose I set a GregorianCalendar's ZONE_OFFSET to -07'00'
     *     calVal = new GregorianCalendar();   // TimeZone is the local default
     *     calVal.set(Calendar.ZONE_OFFSET, -7* MILLIS_PER_HOUR);
     * Four different offsets can be computed from calVal:
     *     calVal.get(Calendar.ZONE_OFFSET)  =>  -07:00
     *     calVal.get(Calendar.ZONE_OFFSET) + calVal.get(Calendar.DST_OFFSET) => -06:00
     *     calVal.getTimeZone().getRawOffset()  =>  -05:00
     *     calVal.getTimeZone().getOffset(calVal.getTimeInMillis())  =>  -04:00
     *
     * Which is correct??? I dunno, though setTimeZone() does seem to affect
     * ZONE_OFFSET, and not vice versa.  One cannot even test whether TimeZone 
     * or ZONE_OFFSET has been set; both have been set by initialization code.
     * TimeZone is initialized to the local default time zone 
     * and ZONE_OFFSET is set from it.
     * 
     * My choice in this DateConverter class has been to set the 
     * initial TimeZone of a GregorianCalendar to GMT. Thereafter
     * the TimeZone is modified with {@link #adjustTimeZoneNicely}.
     *
     * package-private for testing
