Hi,
about getting time from the Internet to a clockwork:
Have a look at the ESP8266, which you can get from china for as low as
4€ in the embodiment of a AMICA board:
Its a controller with some GPIOs and WLAN enabled, freely programmable
(Either with the ARDUINO IDE, or with a LUA or BASIC Firmware.)
Picking up the time from a DAYTIME Server is easier to implement than
NTP, these respond just with a string containing date and time.
At ~100 mA fully on its a good competitor to the Raspies regarding
current consumption.
