Examples with SimpleDateFormat java.text.SimpleDateFormat used on opensource projects

Example 16 with SimpleDateFormat

use of java.text.SimpleDateFormat in project flink by apache.

the class StaticFileServerHandler method setDateHeader.

/**
	 * Sets the "date" header for the HTTP response.
	 *
	 * @param response HTTP response
	 */
private static void setDateHeader(FullHttpResponse response) {
    SimpleDateFormat dateFormatter = new SimpleDateFormat(HTTP_DATE_FORMAT, Locale.US);
    dateFormatter.setTimeZone(GMT_TIMEZONE);
    Calendar time = new GregorianCalendar();
    response.headers().set(DATE, dateFormatter.format(time.getTime()));
}

Example 17 with SimpleDateFormat

use of java.text.SimpleDateFormat in project groovy by apache.

the class InvokeMethodTest method testSetLenientOnDateFormat.

public void testSetLenientOnDateFormat() throws Throwable {
    SimpleDateFormat a = new SimpleDateFormat("MM/dd/yyyy");
    Object value = invoke(a, "setLenient", new Object[] { Boolean.FALSE });
    assertEquals("void method", null, value);
}

Example 18 with SimpleDateFormat

use of java.text.SimpleDateFormat in project groovy by apache.

the class DefaultGroovyStaticMethods method parse.

/**
     * Parse a String into a Date instance using the given pattern and TimeZone.
     * This convenience method acts as a wrapper for {@link java.text.SimpleDateFormat}.
     * <p>
     * Note that a new SimpleDateFormat instance is created for every
     * invocation of this method (for thread safety).
     *
     * @param self   placeholder variable used by Groovy categories; ignored for default static methods
     * @param format pattern used to parse the input string.
     * @param input  String to be parsed to create the date instance
     * @param zone   TimeZone to use when parsing
     * @return a new Date instance representing the parsed input string
     * @throws ParseException if there is a parse error
     * @see java.text.SimpleDateFormat#parse(java.lang.String)
     * @since 2.4.1
     */
public static Date parse(Date self, String format, String input, TimeZone zone) throws ParseException {
    SimpleDateFormat sdf = new SimpleDateFormat(format);
    sdf.setTimeZone(zone);
    return sdf.parse(input);
}

Example 19 with SimpleDateFormat

use of java.text.SimpleDateFormat in project groovy by apache.

the class DateGroovyMethods method format.

/**
     * <p>Shortcut for {@link java.text.SimpleDateFormat} to output a String representation
     * of this calendar instance.  This method respects the Calendar's assigned
     * {@link java.util.TimeZone}, whereas calling <code>cal.time.format('HH:mm:ss')</code>
     * would use the system timezone.
     * <p>Note that Calendar equivalents of <code>date.getDateString()</code>
     * and variants do not exist because those methods are Locale-dependent.
     * Although a Calendar may be assigned a {@link java.util.Locale}, that information is
     * lost and therefore cannot be used to control the default date/time formats
     * provided by these methods.  Instead, the system Locale would always be
     * used.  The alternative is to simply call
     * {@link java.text.DateFormat#getDateInstance(int, java.util.Locale)} and pass the same Locale
     * that was used for the Calendar.
     *
     * @param self    this calendar
     * @param pattern format pattern
     * @return String representation of this calendar with the given format.
     * @see java.text.DateFormat#setTimeZone(java.util.TimeZone)
     * @see java.text.SimpleDateFormat#format(java.util.Date)
     * @see #format(java.util.Date, String)
     * @since 1.6.0
     */
public static String format(Calendar self, String pattern) {
    SimpleDateFormat sdf = new SimpleDateFormat(pattern);
    sdf.setTimeZone(self.getTimeZone());
    return sdf.format(self.getTime());
}
