In the past few years, we have covered plenty of neat VFD clocks here. The Flora is also worth a look. It is a WiFi connected VFD clock that can be programmed in Arduino IDE. This WiFi+NTP VFD clock has a 3D printed case that can be easily replaced. The colors are made with 2x 6 WS2812 addressable LEDs.
The clock has daylight saving support. It comes with a Micro USB connector and works with a 5v power supply. You can find out more about it here.
