You can use time(NULL) to get a time_t, then localtime to get a struct tm representing the time:
time_t now = time(NULL);
struct tm *time_data = localtime(&now);

Then you can use the tm_mon (the month starts at 0, so you'll probably add 1), tm_year, and tm_mday struct elements to get the data that you need.

Example:

time_t ltime =      time(NULL);
char DestinationBuffer[64];
strftime(DestinationBuffer, sizeof(DestinationBuffer), "%y%m%d", gmtime(&ltime));
printf("The date is %s\n", DestinationBuffer);
