How about this:

struct record {
  char skip1;    /* opening quote     */
  char id[11];
  char skip2[3]; /* quote comma quote */
  char time[5];
  char skip3[3]; /* quote comma quote */
  char date[8];
  char skip4;    /* closing quote     */
};

union {
  struct record data;
  char line[32+3]; /* length of record + CR/LF + NULL */
} input;

/* open file */

while (fgets(input.line, sizeof(input.line), fp) != NULL) {
  /* use input.data.id, input.data.time and input.data.date here */
}
