+ C Run-Time Libraries (CRT) Time Management Routines Wrapper Implementation
+ for OpenSSL-based Cryptographic Library.
+
+ 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
