imestamp from localtime mktime

[FrankTheFox]

Hi,


i have to kind of strings (char*)

1) hh:mm:ss
2)YYYY-MM-TThh:mm:ss.000Z (eg.:"2008-09-26T01:51:42.000Z")

long Timestamp(char* CurrentTime)
{
	std::string str = CurrentTime;
	time_t t;
	struct tm * DateTime;
	
	t = time(NULL);
	DateTime = localtime(&t); 
	
	if(str.length() == 8) 
	{
		DateTime->tm_hour = atoi(str.substr(0,2).c_str());
		DateTime->tm_min = atoi(str.substr(3,2).c_str());
		DateTime->tm_sec = atoi(str.substr(6,2).c_str());	
		return (long)mktime(DateTime);
	}
	else if(str.length() == 24)
	{
		DateTime->tm_year = atoi(str.substr(0,4).c_str()) - 1900;
		DateTime->tm_mon = atoi( str.substr(5,2).c_str()) -1;
		DateTime->tm_mday = atoi(str.substr(8,2).c_str());
		DateTime->tm_hour = atoi(str.substr(11,2).c_str());
		DateTime->tm_min = atoi(str.substr(14,2).c_str());
		DateTime->tm_sec = atoi(str.substr(17,2).c_str());	
		return (long)mktime(DateTime);
	}
	else  return (long)t; //timestamp from current time
}

this code works with the input. My question is this the best way or is this code nonsens.

Return: timestamp from selected or current time.

That's as good as it gets, it's a messy business.
