Hi,
 Thanks for the comments, they should be addressed in the next update.
About the times, that's an RFC5280 requirement. 
"CAs conforming to this profile MUST always encode certificate
validity dates through the year 2049 as UTCTime; certificate
validity dates in 2050 or later MUST be encoded as GeneralizedTime."

The notAfter is a date over 2050 (in fact its the 'no well defined
expiration date').

regards,
Nikos
