/***
*time.h - definitions/declarations for time routines
*
* Copyright (c) 1985-1993, Microsoft Corporation. All rights reserved.
*
*Purpose:
* This file has declarations of time routines and defines
* the structure returned by the localtime and gmtime routines and
* used by asctime.
* [ANSI/System V]
*
*Revision History:
* 07-27-87 SKS Added _strdate(), _strtime()
* 10-20-87 JCR Removed "MSC40_ONLY" entries
* 12-11-87 JCR Added "_loadds" functionality
* 12-18-87 JCR Added _FAR_ to declarations
* 01-16-88 JCR Added function versions of daylight/timezone/tzset
* 01-20-88 SKS Change _timezone(n) to _timezone(), _daylight()
* 02-10-88 JCR Cleaned up white space
* 12-07-88 JCR DLL timezone/daylight/tzname now directly refers to data
* 03-14-89 JCR Added strftime() prototype and size_t definition
* 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage
* 08-15-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model)
* 10-30-89 GJF Fixed copyright, removed dummy args from prototypes
* 11-02-89 JCR Changed "DLL" to "_DLL"
* 11-20-89 JCR difftime() always _cdecl (not pascal even under mthread)
* 03-02-90 GJF Added #ifndef _INC_TIME and #include <cruntime.h>
* stuff. Also, removed some (now) useless preprocessor
* directives.
* 03-29-90 GJF Replaced _cdecl with _CALLTYPE1 in prototypes and with
* _VARTYPE1 in variable declarations.
* 08-16-90 SBM Added NULL definition for ANSI compliance
* 11-12-90 GJF Changed NULL to (void *)0.
* 01-21-91 GJF ANSI naming.
* 02-12-91 GJF Only #define NULL if it isn't #define-d.
* 08-20-91 JCR C++ and ANSI naming
* 08-26-91 BWM Added prototypes for _getsystime and _setsystem.
* 09-28-91 JCR ANSI names: DOSX32=prototypes, WIN32=#defines for now
* 01-22-92 GJF Fixed up definitions of global variables for build of,
* and users of, crtdll.dll.
* 03-25-92 DJM POSIX support.
* 08-05-92 GJF Function calling type and variable type macros.
* 08-24-92 PBS Support for Posix TZ variable.
* 01-21-93 GJF Removed support for C6-386's _cdecl.
* 03-10-93 MJB Fixes for Posix TZ stuff.
* 05-05-93 CFW Add wcsftime proto.
* 06-08-93 SKS Cannot #define the old name "timezone" to "_timezone"
* because of conflict conflict with the timezone field
* in struct timeb in <sys/timeb.h>.
