Desktop clock showing time as a DCF77 bistream. The TD-FDCF01A is a table clock that displays time as a DCF77 60-bit stream. It's the opposite of a radio controlled clock - instead of receiving the DCF77 signal, it *displays* the time as that signal. It uses 60 RGB LEDs to show the time, date, and other information, and features a serial interface for customization.

⇒ Ground = Pin G
⇒ Operating Voltage = Pin V
⇒ data = pin T
⇒ Power On/Off = Pin P1
⇒ PIN P1 is an on/off switch and must be set to logic low.
Date and time classes for Arduino supporting the IANA TZ Database time zones to convert epoch seconds to date and time components in different time zones.
