- Sun Aug 28, 2016 8:30 am #53975 So I did some research on EDT and EDST. Currently the UTC adjust for my location is -4 as it is DST. In the winter it will change to -5. Personally I wish we could just stay on EDST all year, I hate loosing evening light in winter.

I thought that timesetup(offset,DST) would perform this function for me. It does not seem to do this. I may just add a button on the final clock that will toggle and persist regular and DST if it truly is not built into the timesetup function. I did this on my aquarium light timer but via the web browser.

Reading time doesn't require any special wait delay. It runs very fast and seeing seconds displayed on the analog panel meter is pretty cool. Can't wait to get the 3rd panel meter. Since the new ESP8266Basic code has had MASSIVE speed improvements, it is capable of nearly everything I want to do right now. The clock code runs perfectly in debug! Soon, I may try to do some BackEMF motor control for my model train control system.

- Sun Aug 28, 2016 10:17 am #53982 Decided to see how adding to hours the proportion of minutes elapsed and to minutes the proportion of seconds elapsed. It makes the panel meters act more like an analog clock, rather than an analog representation of a digital clock.

Here's the code:

HAHA, watching a clock is kind of like watching paint dry! OK, when I get my 3rd panel meter with seconds it's worth it!.
