Writing a code for the Davtron 811 clock! I know how to write a standard digital clock and a elapsed timer. But i need a custom clock. So far i have the system time converted to my LVAR on aircraft load. Maybe the elapsed timer plus the system load time is the trick. I just now realized this as i am writing this post. But now i want to be able to zero the seconds and add minutes and hours. I have done this with analog but for the digital i am having issues. And i do not want to use the default events that can change the system time. I only want to add or subtract time from the system time using LVARS. I tried using E:absolute time, seconds and LVAR ++ LVAR for seconds but when it got to 60 seconds it just kept increasing. Can someone shed some light or post some examples please.
