/***
*inittime.c - contains __init_time
*
* Copyright (c) 1991-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Contains the locale-category initialization function: __init_time().
*
* Each initialization function sets up locale-specific information
* for their category, for use by functions which are affected by
* their locale category.
*
* *** For internal use by setlocale() only ***
*
*Revision History:
* 12-08-91 ETC Created.
* 12-20-91 ETC Updated to use new NLSAPI GetLocaleInfo.
* 12-18-92 CFW Ported to Cuda tree, changed _CALLTYPE4 to _CRTAPI3.
* 12-29-92 CFW Updated to use new _getlocaleinfo wrapper function.
* 01-25-93 KRS Adapted to use ctry or lang dependent data, as approp.
* 02-08-93 CFW Casts to remove warnings.
* 02-16-93 CFW Added support for date and time strings.
* 03-09-93 CFW Use char* time_sep in storeTimeFmt.
* 04-06-93 SKS Replace _CRTAPI* with __cdecl
* 05-20-93 GJF Include windows.h, not individual win*.h files
* 05-24-93 CFW Clean up file (brief is evil).
* 06-11-93 CFW Now inithelp takes void *.
* 09-15-93 CFW Use ANSI conformant "__" names.
* 09-22-93 GJF Merged NT SDK and Cuda versions.
* 04-11-94 GJF Made declaration of __lc_time_curr, and definition of
* __lc_time_intl conditional on ndef DLL_FOR_WIN32S.
* Also, made storeTimeFmt() into a static function.
* 09-06-94 CFW Remove _INTL switch.
* 01-10-95 CFW Debug CRT allocs.
* 08-20-97 GJF Get time format string from Win32 rather than making
* up our own.
* 06-26-98 GJF Changed to support multithread scheme - an old
* __lc_time_data struct must be kept around until all
* affected threads have updated or terminated.
* 03-25-01 PML Add ww_caltype & ww_lcid to __lc_time_data (vs7#196892)
*
