| * Initialize interval patterns locale to this formatter |

| * This code is a bit complicated since |
| * 1. the interval patterns saved in resource bundle files are interval |
| * patterns based on date or time only. |
| * It does not have interval patterns based on both date and time. |
| * Interval patterns on both date and time are algorithm generated. |
| * |
| * For example, it has interval patterns on skeleton "dMy" and "hm", |
| * but it does not have interval patterns on skeleton "dMyhm". |
| * |
| * The rule to genearte interval patterns for both date and time skeleton are |
| * 1) when the year, month, or day differs, concatenate the two original |
| * expressions with a separator between, |
| * For example, interval pattern from "Jan 10, 2007 10:10 am" |
| * to "Jan 11, 2007 10:10am" is |
| * "Jan 10, 2007 10:10 am - Jan 11, 2007 10:10am" |
| * |
| * 2) otherwise, present the date followed by the range expression |
| * for the time. |
