datetime in XP

I am passing in a datetime value into a extended stored procedure, and
thought I could read it into a double. its failing and I am not sure
why.
..
BYTE bType;
ULONG ulMaxLen;
ULONG ulActualLen;
BOOL isParamNull;
int inputParamIndex = 1;
srv_paraminfo(srvroc, inputParamIndex, &bType, &ulMaxLen,
&ulActualLen, NULL, &isParamNull );
BYTE* ldata = new BYTE[ulActualLen];
memset(ldata, '\0', ulActualLen);
srv_paraminfo(Proc, inputParamIndex, &bType, &ulMaxLen, &ulActualLen,
ldata, &isParamNull );
double xdate = (double)*ldata;
delete []ldata;
...
xdate should have the date, but doesn't.
ThanksI figured it out

Datetime conversion under diferent versions of SQL

You are probably passing dates in some regional format (e.g. dd/mm/yyyy) and
this is okay on one server (which may have British language settings) but
not on another (which may have US English language, or mdy dateformat). To
avoid these problems, always pass dates as 'YYYYMMDD'...
