Converting from the internal representation (milliseconds + * since midnight, January 1, 1970) to text is known as "formatting," and converting + * from text to millis is known as "parsing." We currently define only one concrete + * structure UDateFormat, which can handle pretty much all normal + * date formatting and parsing actions. + * <P> + * Date Format helps you to format and parse dates for any locale. Your code can + * be completely independent of the locale conventions for months, days of the + * week, or even the calendar format: lunar vs. solar. + * <P> + * To format a date for the current Locale with default time and date style, + * use one of the static factory methods: + * <pre> + * \code + * UErrorCode status = U_ZERO_ERROR; + * UChar *myString; + * int32_t myStrlen = 0; + * UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL, -1, &status); + * myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, NULL, &status); + * if (status==U_BUFFER_OVERFLOW_ERROR){ + * status=U_ZERO_ERROR; + * myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) ); + * udat_format(dfmt, myDate, myString, myStrlen+1, NULL, &status); + * } + * \endcode + * </pre> + * If you are formatting multiple numbers, it is more efficient to get the + * format and use it multiple times so that the system doesn't have to fetch the + * information about the local language and country conventions multiple times. + * <pre> + * \code + * UErrorCode status = U_ZERO_ERROR; + * int32_t i, myStrlen = 0; + * UChar* myString; + * char buffer[1024]; + * UDate myDateArr[] = { 0.0, 100000000.0, 2000000000.0 }; // test values + * UDateFormat* df = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL, 0, &status); + * for (i = 0; i < 3; i++) { + * myStrlen = udat_format(df, myDateArr[i], NULL, myStrlen, NULL, &status); + * if(status == U_BUFFER_OVERFLOW_ERROR){ + * status = U_ZERO_ERROR; + * myString = (UChar*)malloc(sizeof(UChar) * (myStrlen+1) ); + * udat_format(df, myDateArr[i], myString, myStrlen+1, NULL, &status); + * printf("%s\n", u_austrcpy(buffer, myString) ); + * free(myString); + * } + * } + * \endcode + * </pre> + * To get specific fields of a date, you can use UFieldPosition to + * get specific fields. + * <pre> + * \code + * UErrorCode status = U_ZERO_ERROR; + * UFieldPosition pos; + * UChar *myString; + * int32_t myStrlen = 0; + * char buffer[1024]; + * + * pos.field = 1; // Same as the DateFormat::EField enum + * UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, -1, NULL, 0, &status); + * myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, &pos, &status); + * if (status==U_BUFFER_OVERFLOW_ERROR){ + * status=U_ZERO_ERROR; + * myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) ); + * udat_format(dfmt, myDate, myString, myStrlen+1, &pos, &status); + * } + * printf("date format: %s\n", u_austrcpy(buffer, myString)); + * buffer[pos.endIndex] = 0; // NULL terminate the string. + * printf("UFieldPosition position equals %s\n", &buffer[pos.beginIndex]); + * \endcode + * </pre> + * To format a date for a different Locale, specify it in the call to + * udat_open() + * <pre> + * \code + * UDateFormat* df = udat_open(UDAT_SHORT, UDAT_SHORT, "fr_FR", NULL, -1, NULL, 0, &status); + * \endcode + * </pre> + * You can use a DateFormat API udat_parse() to parse. + * <pre> + * \code + * UErrorCode status = U_ZERO_ERROR; + * int32_t parsepos=0; + * UDate myDate = udat_parse(df, myString, u_strlen(myString), &parsepos, &status); + * \endcode + * </pre> + * You can pass in different options for the arguments for date and time style + * to control the length of the result; from SHORT to MEDIUM to LONG to FULL. + * The exact result depends on the locale, but generally: + * see UDateFormatStyle for more details + * <ul type=round> + * <li> UDAT_SHORT is completely numeric, such as 12/13/52 or 3:30pm + * <li> UDAT_MEDIUM is longer, such as Jan 12, 1952 + * <li> UDAT_LONG is longer, such as January 12, 1952 or 3:30:32pm + * <li> UDAT_FULL is pretty completely specified, such as + * Tuesday, April 12, 1952 AD or 3:30:42pm PST. + * </ul> + * You can also set the time zone on the format if you wish. + * <P> + * You can also use forms of the parse and format methods with Parse Position and + * UFieldPosition to allow you to + * <ul type=round> + * <li> Progressively
