/**

* \file
|
||||
* \brief C API: Format a date interval.
|
||||
*
|
||||
* A UDateIntervalFormat is used to format the range between two UDate values
|
||||
* in a locale-sensitive way, using a skeleton that specifies the precision and
|
||||
* completeness of the information to show. If the range smaller than the resolution
|
||||
* specified by the skeleton, a single date format will be produced. If the range
|
||||
* is larger than the format specified by the skeleton, a locale-specific fallback
|
||||
* will be used to format the items missing from the skeleton.
|
||||
*
|
||||
* For example, if the range is 2010-03-04 07:56 - 2010-03-04 19:56 (12 hours)
|
||||
* - The skeleton jm will produce
|
||||
* for en_US, "7:56 AM - 7:56 PM"
|
||||
* for en_GB, "7:56 - 19:56"
|
||||
* - The skeleton MMMd will produce
|
||||
* for en_US, "Mar 4"
|
||||
* for en_GB, "4 Mar"
|
||||
* If the range is 2010-03-04 07:56 - 2010-03-08 16:11 (4 days, 8 hours, 15 minutes)
|
||||
* - The skeleton jm will produce
|
||||
* for en_US, "3/4/2010 7:56 AM - 3/8/2010 4:11 PM"
|
||||
* for en_GB, "4/3/2010 7:56 - 8/3/2010 16:11"
|
||||
* - The skeleton MMMd will produce
|
||||
* for en_US, "Mar 4-8"
|
||||
* for en_GB, "4-8 Mar"
|
||||
*
|
||||
* Note: the "-" characters in the above sample output will actually be
|
||||
* Unicode 2013, EN_DASH, in all but the last example.
|
||||
*
|
||||
* Note, in ICU 4.4 the standard skeletons for which date interval format data
|
||||
* is usually available are as follows; best results will be obtained by using
|
||||
* skeletons from this set, or those formed by combining these standard skeletons
|
||||
* (note that for these skeletons, the length of digit field such as d, y, or
|
||||
* M vs MM is irrelevant (but for non-digit fields such as MMM vs MMMM it is
|
||||
* relevant). Note that a skeleton involving h or H generally explicitly requests
|
||||
* that time style (12- or 24-hour time respectively). For a skeleton that
|
||||
* requests the locale's default time style (h or H), use 'j' instead of h or H.
|
||||
* h, H, hm, Hm,
|
||||
* hv, Hv, hmv, Hmv,
|
||||
* d,
|
||||
* M, MMM, MMMM,
|
||||
* Md, MMMd,
|
||||
* MEd, MMMEd,
|
||||
* y,
|
||||
* yM, yMMM, yMMMM,
|
||||
* yMd, yMMMd,
|
||||
* yMEd, yMMMEd
|
||||
*
|
||||
* Locales for which ICU 4.4 seems to have a reasonable amount of this data
|
||||
* include:
|
||||
* af, am, ar, be, bg, bn, ca, cs, da, de (_AT), el, en (_AU,_CA,_GB,_IE,_IN...),
|
||||
* eo, es (_AR,_CL,_CO,...,_US) et, fa, fi, fo, fr (_BE,_CH,_CA), fur, gsw, he,
|
||||
* hr, hu, hy, is, it (_CH), ja, kk, km, ko, lt, lv, mk, ml, mt, nb, nl )_BE),
|
||||
* nn, pl, pt (_PT), rm, ro, ru (_UA), sk, sl, so, sq, sr, sr_Latn, sv, th, to,
|
||||
* tr, uk, ur, vi, zh (_SG), zh_Hant (_HK,_MO)
