/**
|
|
* 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.
|
|
* For example, interval pattern from "Jan 10, 2007 10:10 am"
|
|
* to "Jan 10, 2007 11:10am" is
|
|
* "Jan 10, 2007 10:10 am - 11:10am"
|
|
*
|
|
* 2. even a pattern does not request a certion calendar field,
|
|
* the interval pattern needs to include such field if such fields are
|
|
* different between 2 dates.
|
|
* For example, a pattern/skeleton is "hm", but the interval pattern
|
|
* includes year, month, and date when year, month, and date differs.
|
|
*
|
|
* @param status output param set to success/failure code on exit
|
|
* @stable ICU 4.0
