+  This C file implements constant time value for time() and NULL for gmtime()
+  thus should not be used in library instances which require functionality
+  of following APIs which need system time support:
+  1)  RsaGenerateKey
+  2)  RsaCheckKey
+  3)  RsaPkcs1Sign
+  4)  Pkcs7Sign
+  5)  DhGenerateParameter
+  6)  DhGenerateKey
