  C Run-Time Libraries (CRT) Time Management Routines Wrapper Implementation\r
  for OpenSSL-based Cryptographic Library.\r
\r
  This C file implements constant time value for time() and NULL for gmtime()\r
  thus should not be used in library instances which require functionality\r
  of following APIs which need system time support:\r
  1)  RsaGenerateKey\r
  2)  RsaCheckKey\r
  3)  RsaPkcs1Sign\r
  4)  Pkcs7Sign\r
  5)  DhGenerateParameter\r
  6)  DhGenerateKey\r
