+// 1 : time_get, time_put each have their own data internally
+//   use internal data for time and date specifics
+//   use getloc for ctype info
+
+// 2 : time_get, time_put use the ios_base& argument and getloc to
+// retrieve the necessary data.
+//   use getloc for ctype, time and date specifics
+
+// It is my opinion that the language in the standard is sufficiently
+// vague to permit both interpretations. In particular, the interface
+// for time_get and time_put is based on strftime, which as
+// POSIX notes is dependent on LC_TIME. The C++ standard, however,
+// does not specify the equivalent mappings of LC_TIME to time_get and
+// time_put.

+/*
+The problems with the first approach, as above, are numerous.
+
+1) The locale usage and design for formatters and parsers becomes
+   fragmented. On one side, num_put and money_put, and on the other,
+   time_put. This inconsistency is not useful.
+
+2) The data structures for time and date formatting are the largest in
+   the locale library. Making time_put and time_get keep separate
+   copies is inefficient. (Note that time_put and time_get are in the
+   same locale::category).

+-1- Templates time_get<charT,InputIterator> and

+ time_get in the subclauses of lib.category.time only apply to the
+ instantiations required in Tables 51 and 52
+ (lib.locale.category). Their members use their ios_base&,
+ ios_base::iostate&, and fill arguments as described in
+ (lib.locale.categories), and the ctype<> facet, to determine
+ formatting details.

+22.2 - Standard locale categories [lib.locale.categories]
+
+-1- Each of the standard categories includes a family of facets. Some
+ of these implement formatting or parsing of a datum, for use by
+ standard or users' iostream operators << and >>, as members put() and
+ get(), respectively. Each such member function takes an ios_base&
+ argument whose members flags(), precision(), and width(), specify the
+ format of the corresponding datum. (lib.ios.base). Those functions
+ which need to use other facets call its member getloc() to retrieve
+ the locale imbued there. Formatting facets use the character argument
+ fill to fill out the specified width where necessary.
