Here's a couple of videos I made do demonstrate the clock function. First one is in English

"Hello Hackaday, it is Sixteen to Nine" (08:44)

And the second one is in Portuguese

"Olá Hackaday, Oito e quarenta e sete"  (08:47)

On both videos a message has been sent through wifi right after the last minute has finished to flash, but the time function repeats every minute.

The language can be switched by issuing the command @e for English or @b for Portuguese (Brazilian)
