A crash occurs on windows machines when the process culture info doesn't
support the string format representing the x509 certificate timestamp.
Certificate timestamps should be parsed to DateTime using InvariantCulture,
which is what the patch does.

Stack Trace :

System.Security.Cryptography.CryptographicException: Input data cannot be
coded as a valid certificate. ---> System.FormatException: The DateTime
represented by the string is not supported in calendar

format, IFormatProvider provider, DateTimeStyles style) at
