Time Controller is a node-red plugin for RGBW Controller (or other devices) where all channels are managed separatly. It is designed to fade in or fade out each channel in a specified time range
The output value doesn't change smoothly. Instead it only changes once every minute, even if the refresh interval is set to one second. This is because on line 139 (now.seconds(0).millisecond(0)) and line 249 (this.node.now = () => moment().seconds(0).millisecond(0)) in the TimeController.js file.
By replacing the .seconds(0).millisecond(0) part on both of these lines, this issue can be fixed.
Due to the 0.0.15 update there is a issue with the correct start and end value if the intervall is bigger than a minute. I try to fix it as soon as possible. Maybe the intervall type must be selectable.
