// Template functions used by time_get

/* Both time_get and time_put need a structure of type _Time_Info
 * to provide names and abbreviated names for months and days,
 * as well as the am/pm designator.  The month and weekday tables
 * have the all the abbreviated names before all the full names.
 * The _Time_Info tables are initialized using the non-template
 * time_base class, which has a default constructor and two protected.
 * The default one initialize _Time_Info with "C" time info. The
 * protected initialize _time_Info using a _Locale_time instance
 * or using a name( in fact the name is used to build a _Locale_time
 * instance that is then used for initialization). */
