// v.1 - added clock adjustment by Nicu FLORICA (niq_ro)
// v.2 - added outside second line and moved numbers (regenerate others)
// v.2.a - changed to "classical" RTC library from https://github.com/adafruit/RTClib
// v.2.b - line for seconds changed in moving point
// v.3 - changed to ESP8266 -> NTP clock
// v.3.a - added real seconds (fron NTP server)
// v.3.a.1 - reduced flicker ar seconds = 0
