Explanation: the seconds in UTC time are optional.

Actually, this isn't correct. According to Clause 11 of X.690
(Restrictions on BER employed by both CER and DER):

11.8 UTCTime

11.8.1 The encoding shall terminate with "Z", as
described in the ITU-T X.680 | ISO/IEC 8824-1 clause on UTCTime.

11.8.2 The seconds
element shall always be present.

11.8.3 Midnight (GMT) shall be represented in the form:

"YYMMDD000000Z"

where "YYMMDD" represents the day following the midnight in
question.

11.8.4 Examples of valid representations

"920521000000Z"

"920622123421Z"

"920722132100Z"

11.8.5 Examples of invalid representations

"920520240000Z" (midnight represented
incorrectly)

"9207221321Z"
(seconds of "00" omitted)
