c++怎么获取当前时间戳？
方法如下：
time_t curtime = time(0); tm tim; localtime_s(&tim, &curtime); char title[128]; static int s_num = 0; sprintf(title, "%d/%02d/%02d %02d:%02d:%02d", tim.tm_year+1900, tim.tm_mon+1, tim.tm_mday, tim.tm_hour, tim.tm_min, tim.tm_sec);绛旓細linxu涓婃湁鎻愪緵鐩稿簲鐨c璇█鐨勬帴鍙 姣斿time鍑芥暟 浣跨敤time鍑芥暟鍙互鑾峰彇涓涓鏃堕棿鎴 璇ユ椂闂存埑鏄1870骞1鏈1鏃0锛0锛0鑷崇幇鍦ㄧ殑绉掓暟 鐒跺悗鎴戜滑鍙互浣跨敤linux鎻愪緵鐨勪竴浜涜浆鎹㈡帴鍙ｅ皢鍏惰浆鎹负鏃跺垎绉掔殑鏍煎紡 姣斿ctime鎴栬呬篃鍙互浣跨敤gmtime鎴栬卨ocaltime灏嗗叾杞崲涓簊truct tm缁撴瀯浣撶殑鏁版嵁 鎴戜滑鍚屾牱涔熷彲浠ヤ娇鐢╣ettimeofday鍑芥暟...
