/***
*ftime.c - OS/2 return system time
*
* Copyright (c) 1985-1993, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Returns the system date/time in a structure form.
*
*Revision History:
* 03-??-84 RLB initial version
* 05-17-86 SKS ported to OS/2
* 03-09-87 SKS correct Daylight Savings Time flag
* 11-18-87 SKS Change tzset() to __tzset()
* 12-11-87 JCR Added "_LOAD_DS" to declaration
* 10-03-88 JCR 386: Change DOS calls to SYS calls
* 10-04-88 JCR 386: Removed 'far' keyword
* 10-10-88 GJF Made API names match DOSCALLS.H
* 04-12-89 JCR New syscall interface
* 05-25-89 JCR 386 OS/2 calls use '_syscall' calling convention
* 03-20-90 GJF Replaced _LOAD_DS with _CALLTYPE1, added #include
* <cruntime.h>, removed some leftover 16-bit support
* and fixed the copyright. Also, cleaned up the
* formatting a bit.
* 07-25-90 SBM Removed '32' from API names
* 08-13-90 SBM Compiles cleanly with -W3
* 08-20-90 SBM Removed old incorrect, redundant tp->dstflag assignment
* 10-04-90 GJF New-style function declarator.
* 12-04-90 SRW Changed to include <oscalls.h> instead of <doscalls.h>
* 12-06-90 SRW Added _CRUISER_ and _WIN32 conditionals.
* 01-21-91 GJF ANSI naming.
* 01-23-92 GJF Change in time zone field name for Win32, to support
* crtdll.dll [_WIN32_].
* 03-30-93 GJF Revised to use mktime(). Also purged Cruiser support.
* 06-08-93 SKS Change "tmzone" back to "timezone". See h/sys/timeb.h.
* 07-15-93 GJF Call __tzset() instead of _tzset().
