GetDateFormat is one day off

[Anarchi]

When I run the below function, the date gives me 1st DEC 2009 instead of 2nd DEC 2009

I am in Sydney (+10 GMT), its 10:50am here right now. If I change the Windows time to 2:50pm, the date is now correct.

So it looks like the below function not taking into account the +10GMT timezone adjustment?

CString CMyDlg::NLSDateFormat(CTime tm)
{
	SYSTEMTIME systime;
	if (tm == 0) {
		// get the current time
		GetSystemTime(&systime);
	}
	else 
	{
		// convert the CTime
		tm.GetAsSystemTime(systime);
	}

	int size;
	CString cs;
	size = ::GetDateFormat(LOCALE_USER_DEFAULT, DATE_SHORTDATE, &systime, NULL, NULL, 0);
	::GetDateFormat(LOCALE_USER_DEFAULT, DATE_SHORTDATE, &systime, NULL, cs.GetBuffer(size), size);
	cs.ReleaseBuffer();
	return cs;
}

I call the function using NLSDateFormat(0);

Yep, you said it. GetSystemTime is in UTC. Use GetLocalTime instead, and it should be fixed.

No worries I think I figured it out. I changed GetSystemTime to GetLocalTime.

All these time functions are very confusing sometimes lol

[edit] surfdabbler thanks anyway
