-
-Set a time structure to one hour after the current time and print it out:
-
- #include <time.h>
- #include <openssl/asn1.h>
-
- ASN1_TIME *tm;
- time_t t;
- BIO *b;
-
- t = time(NULL);
- tm = ASN1_TIME_adj(NULL, t, 0, 60 * 60);
- b = BIO_new_fp(stdout, BIO_NOCLOSE);
- ASN1_TIME_print(b, tm);
- ASN1_STRING_free(tm);
- BIO_free(b);
-
-Determine if one time is later or sooner than the current time:
-
- int day, sec;
-
- if (!ASN1_TIME_diff(&day, &sec, NULL, to))
- /* Invalid time format */
-
- if (day > 0 || sec > 0)
- printf("Later\n");
- else if (day < 0 || sec < 0)
- printf("Sooner\n");
- else
- printf("Same\n");
