-
-        UCalendar is used for converting between a UDate object and 
-        a set of integer fields such as Year, Month, Day, 
-        Hour, and so on. (A UDate object represents a specific instant 
-        in time with millisecond precision. See UDate for information about 
-        the UDate)
-
-        Types of UCalendar interpret a UDate according to the rules of a 
-        specific calendar system. UCalendar supports Traditional & Gregorian.
-
-        A UCalendar object can produce all the time field values needed to 
-        implement the date-time formatting for a particular language and 
-        calendar style (for example, Japanese-Gregorian, Japanese-Traditional).
-
-        When computing a UDate from time fields, two special circumstances 
-        may arise: there may be insufficient information to compute the UDate 
-        (such as only year and month but no day in the month), or there may be 
-        inconsistent information (such as "Tuesday, July 15, 1996" -- July 15, 
-        1996 is actually a Monday).
-
-        Insufficient information. The calendar will use default information 
-        to specify the missing fields. This may vary by calendar; for the 
-        Gregorian calendar, the default for a field is the same as that of 
-        the start of the epoch: i.e., Year = 1970, Month = January, 
-        Date = 1, etc.
-
-        Inconsistent information. If fields conflict, the calendar will give 
-        preference to fields set more recently. For example, when determining 
-        the day, the calendar will look for one of the following combinations 
-        of fields. The most recent combination, as determined by the most 
-        recently set single field, will be used.
-
-        See http://oss.software.ibm.com/icu/apiref/udat_8h.html for full 
-        details.

+
+        UCalendar is used for converting between a UDate object and 
+        a set of integer fields such as Year, Month, Day, 
+        Hour, and so on. (A UDate object represents a specific instant 
+        in time with millisecond precision. See UDate for information about 
+        the UDate)
+
+        Types of UCalendar interpret a UDate according to the rules of a 
+        specific calendar system. UCalendar supports Traditional & Gregorian.
+
+        A UCalendar object can produce all the time field values needed to 
+        implement the date-time formatting for a particular language and 
+        calendar style (for example, Japanese-Gregorian, Japanese-Traditional).
+
+        When computing a UDate from time fields, two special circumstances 
+        may arise: there may be insufficient information to compute the UDate 
+        (such as only year and month but no day in the month), or there may be 
+        inconsistent information (such as "Tuesday, July 15, 1996" -- July 15, 
+        1996 is actually a Monday).
+
+        Insufficient information. The calendar will use default information 
+        to specify the missing fields. This may vary by calendar; for the 
+        Gregorian calendar, the default for a field is the same as that of 
+        the start of the epoch: i.e., Year = 1970, Month = January, 
+        Date = 1, etc.
+
+        Inconsistent information. If fields conflict, the calendar will give 
+        preference to fields set more recently. For example, when determining 
+        the day, the calendar will look for one of the following combinations 
+        of fields. The most recent combination, as determined by the most 
+        recently set single field, will be used.
+
+        See http://oss.software.ibm.com/icu/apiref/udat_8h.html for full 
+        details.
