使用strftime(您需要先转换time_tstruct tm*):

char buff[20];
struct tm * timeinfo;
timeinfo = localtime (&mtime);
strftime(buff, sizeof(buff), "%b %d %H:%M", timeinfo);

格式:

%b - The abbreviated month name according to the current locale.

%d - The day of the month as a decimal number (range 01 to 31).

%H - The hour as a decimal number using a 24-hour clock (range 00 to 23).

%M - The minute as a decimal number (range 00 to 59).

这是完整的代码:

struct stat info; 
char buff[20]; 
struct tm * timeinfo;

stat(workingFile, &info);

timeinfo = localtime (&(info.st_mtime)); 
strftime(buff, 20, "%b %d %H:%M", timeinfo); 
printf("%s",buff);
