Thanks for this new information.  However, i am aware of smartcard 
environments without mktime().

Who needs mktime to convert an Z-zone Generalizedtime or UTCTime to
some binary value? 

The example that I have shown used gmtime, this is certainly not
a complex function, it is just a small real thing.

As the author of the crypto toolkit that runs on a larger range of embedded
systems than any other [0], I can state that this point is invalid.  I've got
code running on systems without a clock that nevertheless still have
mktime() (OK, so you can't actually check the date against anything once
you've read it, but you can at least read it).  I've never encountered a
system where reading a UTCTime is a problem.
