Not really my cup of tea :-)

This peice of coding calculates what time an event is in aussie time zone,
relative to US times, took about 30 min to make and debug/test.

All times are in the SI 24 hour military timezone format...cause its a pain having to account for semicolons in scanning in integers

Is there something wrong with this code or is it just here for people to learn from? Also this code is in C rather than C# and in at first glance you could use cstdio and cstdlib instead of stdio.h and stdlib.h also conio.h is not standard and MSVC doesn't even have a copy of it, it also makes your code not portable.

Note: I will try compiling it in a bit to see if you actually want me to fix something.
