How do you modify dates and times in a C program? Let me explain further... I receive a message. One field contains a start date and time, another the duration in minutes. I need to calculate the end time. This needs to be able to account for end of day/month/year... It has to be bulletproof. Do I convert to Julian Date/Time? How would I go about that? I have never had to deal with this before...

Thank you in advance,

Boris
