The localtime function converts a time stored as a time_t value and stores the result in a structure of type tm. The long value timer represents the seconds elapsed since midnight (00:00:00), January 1, 1970, coordinated universal time (UTC). This value is usually obtained from the time function.
如果你的double时间单位是秒，可以用localtime这个函数，注意减去你的基准时间和1970/1/1/00/00/00的时间差。
