localtime的问题
一段代码，把秒数转换为年月日时分秒，放到Visual Studio 2005中编译，出现如下错误：
error C2664: 'localtime' : cannot convert parameter 1 from 'long *__w64 ' to 'const time_t *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
请问如何修改？
string get_date_time(long t)
{
char datetime[32];
struct tm *newtime;
string ret;
newtime = localtime(&t);
sprintf(datetime,"%04d-%02d-%02d %02d:%02d:%02d",
newtime->tm_year+1900,
newtime->tm_mon+1,
newtime->tm_mday,
newtime->tm_hour,
newtime->tm_min,
newtime->tm_sec);
ret = datetime;
return ret;
}

struct tm *newtime;
char am_pm[] = "AM";
__time64_t long_time;
_time64( &long_time ); // Get time as 64-bit integer.
// Convert to local time.
newtime = _localtime64( &long_time ); // C4996

看错了 强制转换下试试
stonewater 2010-07-26
newtime = localtime((time_t*)&t);

SYSTEMTIME Time;
GetLocalTime(&Time);
GetLocalTime(&Time);
