| 609 | * Initialize interval patterns locale to this formatter | |
| 610 | * | |
| 611 | * This code is a bit complicated since | |
| 612 | * 1. the interval patterns saved in resource bundle files are interval | |
| 613 | * patterns based on date or time only. | |
| 614 | * It does not have interval patterns based on both date and time. | |
| 615 | * Interval patterns on both date and time are algorithm generated. | |
| 616 | * | |
| 617 | * For example, it has interval patterns on skeleton "dMy" and "hm", | |
| 618 | * but it does not have interval patterns on skeleton "dMyhm". | |
| 619 | * | |
| 620 | * The rule to genearte interval patterns for both date and time skeleton are | |
| 621 | * 1) when the year, month, or day differs, concatenate the two original | |
| 622 | * expressions with a separator between, | |
| 623 | * For example, interval pattern from "Jan 10, 2007 10:10 am" | |
| 624 | * to "Jan 11, 2007 10:10am" is | |
| 625 | * "Jan 10, 2007 10:10 am - Jan 11, 2007 10:10am" | |
| 626 | * | |
| 627 | * 2) otherwise, present the date followed by the range expression | |
| 628 | * for the time. | |
| 629 | * For example, interval pattern from "Jan 10, 2007 10:10 am" | |
| 630 | * to "Jan 10, 2007 11:10am" is | |
| 631 | * "Jan 10, 2007 10:10 am - 11:10am" | |
| 632 | * | |
| 633 | * 2. even a pattern does not request a certion calendar field, | |
| 634 | * the interval pattern needs to include such field if such fields are | |
| 635 | * different between 2 dates. | |
| 636 | * For example, a pattern/skeleton is "hm", but the interval pattern | |
| 637 | * includes year, month, and date when year, month, and date differs. | |
| 638 | * | |
| 639 | * @param status output param set to success/failure code on exit | |
| 729e4ab9 | 640 | * @stable ICU 4.0 |
