UTC programming in C++

How do I write code that will automatically correct itself when Daylight Savings Time changes to Standard Time. I.E. I'm in the Central Time Zone. I'm writing for a personal program that needs to display UTC time all the time. I understand how to calculate it in C++ today, but, there is no code example for when the change occurs. Today, I'm -5 hrs from GMT...in a month or two it will be -6 hrs. In other words, how do I write code to "know" the specific dates of change are, especially since the USA keeps changing those dates????? Thanks for any help!! | |

| Well, your OS should keep track of this as long as it connected to the internet. They just use NTP or SNTP. | |
