Y 1..n 1997 Year (in "Week of Year" based calendars). Normally the length specifies the padding, but for two letters it also + * specifies the maximum length. This year designation is used in ISO year-week calendar as defined by ISO 8601, but can + * be used in non-Gregorian based calendar systems where week date processing is desired. May not always be the same value + * as calendar year.
u 1..n 4601 Extended year. This is a single number designating the year of this calendar system, encompassing all supra-year fields. + * For example, for the Julian calendar system, year numbers are positive, with an era of BCE or CE. An extended year value + * for the Julian calendar system assigns positive values to CE years and negative values to BCE years, with 1 BCE being year 0.
U 1..3 甲子 Cyclic year name. Calendars such as the Chinese lunar calendar (and related calendars) and the Hindu calendars + * use 60-year cycles of year names. Use one through three letters for the abbreviated name, four for the full (wide) + * name, or five for the narrow name (currently the data only provides abbreviated names, which will be used for + * all requested name widths). If the calendar does not provide cyclic year name data, or if the year value to be + * formatted is out of the range of years for which cyclic name data is provided, then numeric formatting is used + * (behaves like 'y').

F 1 2 Day of Week in Month. The example is for the 2nd Wed in July
g 1..n 2451334 Modified Julian day. This is different from the conventional Julian day number in two regards. First, it demarcates + * days at local zone midnight, rather than noon GMT. Second, it is a local number; that is, it depends on the local + * time zone. It can be thought of as a single number that encompasses all the date-related fields.

K 1..2 0 Hour [0-11]. When used in a skeleton, only matches K or h, see above. Use KK for zero padding.
k 1..2 24 Hour [1-24]. When used in a skeleton, only matches k or H, see above. Use kk for zero padding.
minute m 1..2 59 Minute. Use "m" to show the minimum number of digits, or "mm" to always show two digits (zero-padding if necessary, + * e.g. "08").
second s 1..2 12 Second. Use "s" to show the minimum number of digits, or "ss" to always show two digits (zero-padding if necessary, + * e.g. "08").
S 1..n 3450 Fractional Second - truncates (like other time fields) to the count of letters when formatting. Appends zeros if more + * than 3 letters specified. Truncates at three significant digits when parsing. (example shows display using pattern + * SSSS for seconds value 12.34567)
A 1..n 69540000 Milliseconds in day. This field behaves exactly like a composite of all time-related fields, not including + * the zone fields. As such, it also reflects discontinuities of those fields on DST transition days. On a day of DST + * onset, it will jump forward. On a day of DST cessation, it will jump backward. This reflects the fact that is must + * be combined with the offset field to obtain a unique local time value.
zone z 1..3 PDT The short specific non-location format. Where that is unavailable, falls back to the short localized + * GMT format ("O").
4 Pacific Daylight Time The long specific non-location format. Where that is unavailable, falls back to the long localized + * GMT format ("OOOO").
Z 1..3 -0800 The ISO8601 basic format with hours, minutes and optional seconds fields. The format is equivalent to + * RFC 822 zone format (when optional seconds field is absent). This is equivalent to the "xxxx" specifier.
4 GMT-8:00 The long localized GMT format. This is equivalent to the "OOOO" specifier.
5 -08:00
+ * -07:52:58 + * 		The ISO8601 extended format with hours, minutes and optional seconds fields. The ISO8601 UTC indicator "Z" + * is used when local time offset is 0. This is equivalent to the "XXXXX" specifier.
O 1 GMT-8 The short localized GMT format.
4 GMT-08:00 The long localized GMT format.
v 1 PT The short generic non-location format. Where that is unavailable, falls back to the generic location + * format ("VVVV"), then the short localized GMT format as the final fallback.
4 Pacific Time The long generic non-location format. Where that is unavailable, falls back to generic location + * format ("VVVV").
V 1 uslax The short time zone ID. Where that is unavailable, the special short time zone ID unk (Unknown Zone) is used.
+ * Note: This specifier was originally used for a variant of the short specific non-location format, but it was + * deprecated in the later version of the LDML specification. In CLDR 23/ICU 51, the definition of the + * specifier was changed to designate a short time zone ID. + *
2 America/Los_Angeles The long time zone ID.
3 Los Angeles The exemplar city (location) for the time zone. Where that is unavailable, the localized exemplar city name for the + * special zone Etc/Unknown is used as the fallback (for example, "Unknown City").
4 Los Angeles Time The generic location format. Where that is unavailable, falls back to the long localized GMT + * format ("OOOO"; Note: Fallback is only necessary with a GMT-style Time Zone ID, like Etc/GMT-830.)
+ * This is especially useful when presenting possible timezone choices for user selection, since the naming is more + * uniform than the "v" format. + *

+ * + * Any characters in the pattern that are not in the ranges of ['a'..'z'] and ['A'..'Z'] will be treated as quoted text. + * For instance, characters like ':', '.', ' ', '#' and '@' will appear in the resulting time text even they are not embraced + * within single quotes. + * + * A pattern containing any invalid pattern letter will result in a failing UErrorCode result during formatting or parsing. + * + * When parsing a date string using the abbreviated year pattern ("y" or "yy"), Simple Date Format must interpret the abbreviated + * year relative to some century. It does this by adjusting dates to be within 80 years before and 20 years after the time the + * Simple Date Format instance is created. For example, using a pattern of "MM/dd/yy" and a Simple Date Format instance created + * on Jan 1, 1997, the string "01/11/12" would be interpreted as Jan 11, 2012 while the string "05/04/64" would be interpreted + * as May 4, 1964. During parsing, only strings consisting of exactly two digits will be parsed into the default century. + * Any other numeric string, such as a one digit string, a three or more digit string, or a two digit string that isn't all digits + * (for example, "-1"), is interpreted literally. So "01/02/3" or "01/02/003" are parsed (for the Gregorian calendar), using the + * same pattern, as Jan 2, 3 AD. Likewise (but only in lenient parse mode, the default) "01/02/-3" is parsed as Jan 2, 4 BC. + * + * If the year pattern has more than two 'y' characters, the year is interpreted literally, regardless of the number of digits. + * So using the pattern "MM/dd/yyyy", "01/11/12" parses to Jan 11, 12 A.D. + * + * When numeric fields abut one another directly, with no intervening delimiter characters, they constitute a run of abutting + * numeric fields. Such runs are parsed specially. For example, the format "HHmmss" parses the input text "123456" to 12:34:56, + * parses the input text "12345" to 1:23:45, and fails to parse "1234". In other words, the leftmost field of the run is flexible, + * while the others keep a fixed width. If the parse fails anywhere in the run, then the leftmost field is shortened by one + * character, and the entire run is parsed again. This is repeated until either the parse succeeds or the leftmost field is one + * character in length. If the parse still fails at that point, the parse of the run fails. + * + * For time zones that have no names, Simple Date Format uses strings GMT+hours:minutes or GMT-hours:minutes. + * + * The calendar defines what is the first day of the week, the first week of the year, whether hours are zero based or not + * (0 vs 12 or 24), and the timezone. There is one common number format to handle all the numbers; the digit count is handled + * programmatically according to the pattern. + */ + +/** + * @addtogroup CAPI_BASE_UTILS_I18N_SIMPLE_DATE_FORMAT_MODULE + * @{ + */ + +/** + * @brief Creates a simple date format object using the default pattern for the default locale. + * @since_tizen 5.0 + * @remarks The created object should be released by the caller with the + * i18n_simple_date_fmt_destroy() function. + * + * @param[out] simple_date_fmt The created simple date format object + * + * @return @c 0 on success, otherwise a negative error value + * @retval #I18N_ERROR_NONE Successful + * @retval #I18N_ERROR_INVALID_PARAMETER Invalid function parameter + * @retval #I18N_ERROR_OUT_OF_MEMORY Out of memory + */ +int i18n_simple_date_fmt_create(i18n_simple_date_fmt_h *simple_date_fmt);
