It allows for formatting (millis -> text), michael@0: * parsing (text -> millis), and normalization. Formats/Parses a date or time, michael@0: * which is the standard milliseconds since 24:00 GMT, Jan 1, 1970. michael@0: *

michael@0: * Clients are encouraged to create a date-time formatter using DateFormat::getInstance(), michael@0: * getDateInstance(), getDateInstance(), or getDateTimeInstance() rather than michael@0: * explicitly constructing an instance of SimpleDateFormat. This way, the client michael@0: * is guaranteed to get an appropriate formatting pattern for whatever locale the michael@0: * program is running in. However, if the client needs something more unusual than michael@0: * the default patterns in the locales, he can construct a SimpleDateFormat directly michael@0: * and give it an appropriate pattern (or use one of the factory methods on DateFormat michael@0: * and modify the pattern after the fact with toPattern() and applyPattern(). michael@0: * michael@0: *

Date and Time Patterns:

michael@0: * michael@0: *

Date and time formats are specified by date and time pattern strings. michael@0: * Within date and time pattern strings, all unquoted ASCII letters [A-Za-z] are reserved michael@0: * as pattern letters representing calendar fields. SimpleDateFormat supports michael@0: * the date and time formatting algorithm and pattern letters defined by michael@0: * UTS#35 michael@0: * Unicode Locale Data Markup Language (LDML) and further documented for ICU in the michael@0: * ICU michael@0: * User Guide.

Y1..n1997Year (in "Week of Year" based calendars). Normally the length specifies the padding, michael@0: * but for two letters it also specifies the maximum length. This year designation is used in ISO michael@0: * year-week calendar as defined by ISO 8601, but can be used in non-Gregorian based calendar systems michael@0: * where week date processing is desired. May not always be the same value as calendar year.
u1..n4601Extended year. This is a single number designating the year of this calendar system, encompassing michael@0: * all supra-year fields. For example, for the Julian calendar system, year numbers are positive, with an michael@0: * era of BCE or CE. An extended year value for the Julian calendar system assigns positive values to CE michael@0: * years and negative values to BCE years, with 1 BCE being year 0.
U1..3甲子Cyclic year name. Calendars such as the Chinese lunar calendar (and related calendars) michael@0: * and the Hindu calendars use 60-year cycles of year names. Use one through three letters for the abbreviated michael@0: * name, four for the full name, or five for the narrow name (currently the data only provides abbreviated names, michael@0: * which will be used for all requested name widths). If the calendar does not provide cyclic year name data, michael@0: * or if the year value to be formatted is out of the range of years for which cyclic name data is provided, michael@0: * then numeric formatting is used (behaves like 'y').

V1uslaxThe short time zone ID. michael@0: * Where that is unavailable, the special short time zone ID unk (Unknown Zone) is used.
michael@0: * Note: This specifier was originally used for a variant of the short specific non-location format, michael@0: * but it was deprecated in the later version of the LDML specification. In CLDR 23/ICU 51, the definition of michael@0: * the specifier was changed to designate a short time zone ID.
2America/Los_AngelesThe long time zone ID.
3Los AngelesThe exemplar city (location) for the time zone. michael@0: * Where that is unavailable, the localized exemplar city name for the special zone Etc/Unknown is used michael@0: * as the fallback (for example, "Unknown City").
4Los Angeles TimeThe generic location format. michael@0: * Where that is unavailable, falls back to the long localized GMT format ("OOOO"; michael@0: * Note: Fallback is only necessary with a GMT-style Time Zone ID, like Etc/GMT-830.)
michael@0: * This is especially useful when presenting possible timezone choices for user selection, michael@0: * since the naming is more uniform than the "v" format.

michael@0:  * \endcode
michael@0:  *
michael@0: * In the above example, the time value "currentTime_2" obtained from parsing michael@0: * will be equal to currentTime_1. However, they may not be equal if the am/pm michael@0: * marker 'a' is left out from the format pattern while the "hour in am/pm" michael@0: * pattern symbol is used. This information loss can happen when formatting the michael@0: * time in PM. michael@0: * michael@0: *

michael@0: * When parsing a date string using the abbreviated year pattern ("y" or "yy"), michael@0: * SimpleDateFormat must interpret the abbreviated year michael@0: * relative to some century. It does this by adjusting dates to be michael@0: * within 80 years before and 20 years after the time the SimpleDateFormat michael@0: * instance is created. For example, using a pattern of "MM/dd/yy" and a michael@0: * SimpleDateFormat instance created on Jan 1, 1997, the string michael@0: * "01/11/12" would be interpreted as Jan 11, 2012 while the string "05/04/64" michael@0: * would be interpreted as May 4, 1964. michael@0: * During parsing, only strings consisting of exactly two digits, as defined by michael@0: * Unicode::isDigit(), will be parsed into the default century. michael@0: * Any other numeric string, such as a one digit string, a three or more digit michael@0: * string, or a two digit string that isn't all digits (for example, "-1"), is michael@0: * interpreted literally. So "01/02/3" or "01/02/003" are parsed (for the michael@0: * Gregorian calendar), using the same pattern, as Jan 2, 3 AD. Likewise (but michael@0: * only in lenient parse mode, the default) "01/02/-3" is parsed as Jan 2, 4 BC. michael@0: * michael@0: *

michael@0: * If the year pattern has more than two 'y' characters, the year is michael@0: * interpreted literally, regardless of the number of digits. So using the michael@0: * pattern "MM/dd/yyyy", "01/11/12" parses to Jan 11, 12 A.D. michael@0: * michael@0: *

michael@0: * When numeric fields abut one another directly, with no intervening delimiter michael@0: * characters, they constitute a run of abutting numeric fields. Such runs are michael@0: * parsed specially. For example, the format "HHmmss" parses the input text michael@0: * "123456" to 12:34:56, parses the input text "12345" to 1:23:45, and fails to michael@0: * parse "1234". In other words, the leftmost field of the run is flexible, michael@0: * while the others keep a fixed width. If the parse fails anywhere in the run, michael@0: * then the leftmost field is shortened by one character, and the entire run is michael@0: * parsed again. This is repeated until either the parse succeeds or the michael@0: * leftmost field is one character in length. If the parse still fails at that michael@0: * point, the parse of the run fails. michael@0: * michael@0: *
