Displaying Time/Date in current locale
Ronen Lamdan -- ronenl@netmanage.co.il
Thursday, September 19, 1996
Environment: VC++ 4.0 and 1.52, Win 95/NT and 3.11
I would like to display a time/date string according to the international time/date
settings on the current machine. For example, in the US I would display:
9/19/96 8:26 pm
and in Europe:
19/9/96 20:26
or however the user set up his control panel. So how do I get the display format
in 16-bits? In 32-bits it's easy, just use GetDateFormat/GetTimeFormat as below.
Is there a solution that would work equally well in 16 AND 32-bits?
CString timeString;
CTime* t = GetDate();
char buf[50];
SYSTEMTIME systime;
systime.wYear = (WORD)t->GetYear();
systime.wMonth = (WORD)t->GetMonth();
systime.wDayOfWeek = (WORD)t->GetDayOfWeek() - 1;// 0-index Vs. 1-index
systime.wDay = (WORD)t->GetDay();
systime.wHour = (WORD)t->GetHour();
systime.wMinute = (WORD)t->GetMinute();
systime.wSecond = (WORD)t->GetSecond();
systime.wMilliseconds = 0;
if (GetDateFormat(NULL, DATE_SHORTDATE, &systime, NULL, buf, sizeof(buf)))
{
timeString = CString(buf);
if (GetTimeFormat(NULL, TIME_NOSECONDS, &systime, NULL, buf, 20))
timeString += CString(" ") + CString(buf);
}

There's certainly such a solution, but you'll have to write it yourself or find
it from a third party. Win16 doesn't support locales very strongly, while Win32
does. In Win16, you'll need to get the date and time format rules that the user
has set up in Control Panel. That information is available in SYSTEM.INI, if I
remember correctly--it might be in WIN.INI.
After that, you'll need to parse the string description of what the user
wants and
write your own formatting routine.
Neither MFC, Win16, nor the CRTL provide support for this. You might be able to
use the same support from OLE automation that MFC uses under Win32--I really
can't remmeber if that support is provided by 16-bit OLE. Have a look at the
implementation of the MFC 4.x class COleDateTime() to get a starting point.

Hi !
his is easy, use the Format() function in COleDateTime !

Ronen,
I'm not aware of any specific Win16 facility to do this for you, but you could write
your own wrapper to hide differences between the platforms and get the relevant
information from the win.ini [Intl] section.
You can use GetProfileInt/String to retreive the iTime, sTime, s1159, s2359,
sShortDate etc. settings and format the result yourself.

In WIN.INI, the Intl section you can find the entries you need. It doesn't
matter if the system is a 16 or 32 bit one.

Hi Ronen
I have this problem as well in 16 bit Windows, so if you hear of a
solution I'd be grateful to know about it. The root problem here is
that the 16-bit runtime stuff only supports the "C" locale, and so
strftime() etc can't do any others.

Folks,
May I suggest ftp.microsoft.com/Softlib/MSLFILES/WINTIME.EXE - a self extracting
file with everything you need and it works.

If you would like some sample 16 bit "c" code that does it, check out
Microsoft's sample program WINTIME.EXE. It should be available as a
self-extracting file from the Microsoft Software Library (MSL) on the
following services:
- Microsoft Download Service (MSDL)
Dial (206) 936-6735 to connect to MSDL
Download WINTIME.EXE
- Internet (anonymous FTP)
ftp ftp.microsoft.com
Change to the \SOFTLIB\MSLFILES directory
Get WINTIME.EXE

I afraid you will have to understand and parse the contents of the
win.ini file. There was an article in an MSDN article from a number of
years back. You might also want to have a look at a number of classes
i have developed for handing date and times. Its home page is
http://indigo.ie/~pjn/dtime.html.

WINTIME is a nice; but here is a little more quick & dirty method using
OLE variants and MFC...
CString InternationalDateTimeString(int iYear,int iMonth,int iDay,int
iHour,int iMinute,int iSecond)
{
try
{
COleVariant
varDt(COleDateTime(iYear,iMonth,iDay,iHour,iMinute,iSecond));
varDt.ChangeType(VT_BSTR);
return CString(V_BSTR(&varDt));
}
catch (CException* e)
{
e->ReportError();
e->Delete();
}
return CString("...default...");
}
...
CString string = InternationalDateTimeString(1999, 1, 25, 23, 45, 58);

I too have the 16-bit date/time display problem, and I tried WinTime
quickly this morning. It works under Western Windows, but not at all
well in Eastern (DBCS) versions. I've not looked into it much, but I
didn't see a lot of use of AnsiNext, so I guess they didn't even try.
Also, it gets the day and month texts from the application rather than
from Windows, which is a shame, given that the control panel can
obviously manage it.
A good starting point, though.
