585 | * Initialize interval patterns locale to this formatter | |
586 | * | |
587 | * This code is a bit complicated since | |
588 | * 1. the interval patterns saved in resource bundle files are interval | |
589 | * patterns based on date or time only. | |
590 | * It does not have interval patterns based on both date and time. | |
591 | * Interval patterns on both date and time are algorithm generated. | |
592 | * | |
593 | * For example, it has interval patterns on skeleton "dMy" and "hm", | |
594 | * but it does not have interval patterns on skeleton "dMyhm". | |
595 | * | |
596 | * The rule to genearte interval patterns for both date and time skeleton are | |
597 | * 1) when the year, month, or day differs, concatenate the two original | |
598 | * expressions with a separator between, | |
599 | * For example, interval pattern from "Jan 10, 2007 10:10 am" | |
600 | * to "Jan 11, 2007 10:10am" is | |
601 | * "Jan 10, 2007 10:10 am - Jan 11, 2007 10:10am" | |
602 | * | |
603 | * 2) otherwise, present the date followed by the range expression | |
604 | * for the time. | |
605 | * For example, interval pattern from "Jan 10, 2007 10:10 am" | |
606 | * to "Jan 10, 2007 11:10am" is | |
607 | * "Jan 10, 2007 10:10 am - 11:10am" | |
608 | * | |
609 | * 2. even a pattern does not request a certion calendar field, | |
610 | * the interval pattern needs to include such field if such fields are | |
611 | * different between 2 dates. | |
612 | * For example, a pattern/skeleton is "hm", but the interval pattern | |
613 | * includes year, month, and date when year, month, and date differs. | |
614 | * | |
615 | * @param status output param set to success/failure code on exit | |
729e4ab9 | 616 | * @stable ICU 4.0 |
