39 /* */
40 /* This function sets up a function pointer that TLS will invoke when */

44 /* The function is expected to return the current GMT in UNIX 32-bit */
45 /* format (seconds since the midnight starting Jan 1, 1970, UTC, */
46 /* ignoring leap seconds), as per the ClientHello requirements in the */
47 /* TLS RFC 5246. */
