/** @file
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
