the class Date method parse.

/**
 * Attempts to interpret the string <tt>s</tt> as a representation
 * of a date and time. If the attempt is successful, the time
 * indicated is returned represented as the distance, measured in
 * milliseconds, of that time from the epoch (00:00:00 GMT on
 * January 1, 1970). If the attempt fails, an
 * <tt>IllegalArgumentException</tt> is thrown.
 * <p>
 * It accepts many syntaxes; in particular, it recognizes the IETF
 * standard date syntax: "Sat, 12 Aug 1995 13:30:00 GMT". It also
 * understands the continental U.S. time-zone abbreviations, but for
 * general use, a time-zone offset should be used: "Sat, 12 Aug 1995
 * 13:30:00 GMT+0430" (4 hours, 30 minutes west of the Greenwich
 * meridian). If no time zone is specified, the local time zone is
 * assumed. GMT and UTC are considered equivalent.
 * <p>
 * The string <tt>s</tt> is processed from left to right, looking for
 * data of interest. Any material in <tt>s</tt> that is within the
 * ASCII parenthesis characters <tt>(</tt> and <tt>)</tt> is ignored.
 * Parentheses may be nested. Otherwise, the only characters permitted
 * within <tt>s</tt> are these ASCII characters:
 * <blockquote><pre>
 * abcdefghijklmnopqrstuvwxyz
 * ABCDEFGHIJKLMNOPQRSTUVWXYZ
 * 0123456789,+-:/</pre></blockquote>
 * and whitespace characters.<p>
 * A consecutive sequence of decimal digits is treated as a decimal
 * number:<ul>
 * <li>If a number is preceded by <tt>+</tt> or <tt>-</tt> and a year
 *     has already been recognized, then the number is a time-zone
 *     offset. If the number is less than 24, it is an offset measured
 *     in hours. Otherwise, it is regarded as an offset in minutes,
 *     expressed in 24-hour time format without punctuation. A
 *     preceding <tt>-</tt> means a westward offset. Time zone offsets
 *     are always relative to UTC (Greenwich). Thus, for example,
 *     <tt>-5</tt> occurring in the string would mean "five hours west
 *     of Greenwich" and <tt>+0430</tt> would mean "four hours and
 *     thirty minutes east of Greenwich." It is permitted for the
 *     string to specify <tt>GMT</tt>, <tt>UT</tt>, or <tt>UTC</tt>
 *     redundantly-for example, <tt>GMT-5</tt> or <tt>utc+0430</tt>.
 * <li>The number is regarded as a year number if one of the
 *     following conditions is true:
 * <ul>
 *     <li>The number is equal to or greater than 70 and followed by a
 *         space, comma, slash, or end of string
 *     <li>The number is less than 70, and both a month and a day of
 *         the month have already been recognized</li>
 * </ul>
 *     If the recognized year number is less than 100, it is
 *     interpreted as an abbreviated year relative to a century of
 *     which dates are within 80 years before and 19 years after
 *     the time when the Date class is initialized.
 *     After adjusting the year number, 1900 is subtracted from
 *     it. For example, if the current year is 1999 then years in
 *     the range 19 to 99 are assumed to mean 1919 to 1999, while
 *     years from 0 to 18 are assumed to mean 2000 to 2018.  Note
 *     that this is slightly different from the interpretation of
 *     years less than 100 that is used in {@link java.text.SimpleDateFormat}.
 * <li>If the number is followed by a colon, it is regarded as an hour,
 *     unless an hour has already been recognized, in which case it is
 *     regarded as a minute.
 * <li>If the number is followed by a slash, it is regarded as a month
 *     (it is decreased by 1 to produce a number in the range <tt>0</tt>
 *     to <tt>11</tt>), unless a month has already been recognized, in
 *     which case it is regarded as a day of the month.
 * <li>If the number is followed by whitespace, a comma, a hyphen, or
 *     end of string, then if an hour has been recognized but not a
 *     minute, it is regarded as a minute; otherwise, if a minute has
 *     been recognized but not a second, it is regarded as a second;
 *     otherwise, it is regarded as a day of the month. </ul><p>
 * A consecutive sequence of letters is regarded as a word and treated
 * as follows:<ul>
 * <li>A word that matches <tt>AM</tt>, ignoring case, is ignored (but
 *     the parse fails if an hour has not been recognized or is less
 *     than <tt>1</tt> or greater than <tt>12</tt>).
 * <li>A word that matches <tt>PM</tt>, ignoring case, adds <tt>12</tt>
 *     to the hour (but the parse fails if an hour has not been
 *     recognized or is less than <tt>1</tt> or greater than <tt>12</tt>).
 * <li>Any word that matches any prefix of <tt>SUNDAY, MONDAY, TUESDAY,
 *     WEDNESDAY, THURSDAY, FRIDAY</tt>, or <tt>SATURDAY</tt>, ignoring
 *     case, is ignored. For example, <tt>sat, Friday, TUE</tt>, and
 *     <tt>Thurs</tt> are ignored.
 * <li>Otherwise, any word that matches any prefix of <tt>JANUARY,
 *     FEBRUARY, MARCH, APRIL, MAY, JUNE, JULY, AUGUST, SEPTEMBER,
 *     OCTOBER, NOVEMBER</tt>, or <tt>DECEMBER</tt>, ignoring case, and
 *     considering them in the order given here, is recognized as
 *     specifying a month and is converted to a number (<tt>0</tt> to
 *     <tt>11</tt>). For example, <tt>aug, Sept, april</tt>, and
 *     <tt>NOV</tt> are recognized as months. So is <tt>Ma</tt>, which
 *     is recognized as <tt>MARCH</tt>, not <tt>MAY</tt>.
 * <li>Any word that matches <tt>GMT, UT</tt>, or <tt>UTC</tt>, ignoring
 *     case, is treated as referring to UTC.
 * <li>Any word that matches <tt>EST, CST, MST</tt>, or <tt>PST</tt>,
 *     ignoring case, is recognized as referring to the time zone in
 *     North America that is five, six, seven, or eight hours west of
 *     Greenwich, respectively. Any word that matches <tt>EDT, CDT,
 *     MDT</tt>, or <tt>PDT</tt>, ignoring case, is recognized as
 *     referring to the same time zone, respectively, during daylight
 *     saving time.</ul><p>
 * Once the entire string s has been scanned, it is converted to a time
 * result in one of two ways. If a time zone or time-zone offset has been
 * recognized, then the year, month, day of month, hour, minute, and
 * second are interpreted in UTC and then the time-zone offset is
 * applied. Otherwise, the year, month, day of month, hour, minute, and
 * second are interpreted in the local time zone.
 *
 * @param   s   a string to be parsed as a date.
 * @return  the number of milliseconds since January 1, 1970, 00:00:00 GMT
 *          represented by the string argument.
 * @see     java.text.DateFormat

use of sun.util.calendar.BaseCalendar in project j2objc by google.

the class Date method UTC.

/**
 * Determines the date and time based on the arguments. The
 * arguments are interpreted as a year, month, day of the month,
 * hour of the day, minute within the hour, and second within the
 * minute, exactly as for the <tt>Date</tt> constructor with six
 * arguments, except that the arguments are interpreted relative
 * to UTC rather than to the local time zone. The time indicated is
 * returned represented as the distance, measured in milliseconds,
 * of that time from the epoch (00:00:00 GMT on January 1, 1970).
 *
 * @param   year    the year minus 1900.
 * @param   month   the month between 0-11.
 * @param   date    the day of the month between 1-31.
 * @param   hrs     the hours between 0-23.
 * @param   min     the minutes between 0-59.
 * @param   sec     the seconds between 0-59.
 * @return  the number of milliseconds since January 1, 1970, 00:00:00 GMT for
 *          the date and time specified by the arguments.
 * @see     java.util.Calendar
 * @deprecated As of JDK version 1.1,
 * replaced by <code>Calendar.set(year + 1900, month, date,
 * hrs, min, sec)</code> or <code>GregorianCalendar(year + 1900,
 * month, date, hrs, min, sec)</code>, using a UTC
 * <code>TimeZone</code>, followed by <code>Calendar.getTime().getTime()</code>.
