For those who avoid googlegroups with a passion, and/or don't have
internet access, the subject of that thread is "date-time comparison,
aware vs naive", on this same mailing list.

You can save people a lot of time if you just think before posting. 
What do you define as failure?  is your motherboard smoking, or is the
final result off by a second?
Please reread my last message on the previous thread.  If you want us to
give you code advice, show us what you're doing, don't just describe it
in vague terms.

When accepting input from a user, consider their environment.  Perhaps
they're in a different timezone than your program (or your native
location), or use some other ordering for the date (for example, the
Japanese sensibly put year first, then month, then day.  Other regions
have different conventions.  If you can't detect the user environment,
then you'd better tell them yours.  For example,by prompting for day,
month, and year separately.
