While the climate clock is powered off a small coin cell battery powers a clock that allows the computer to still keep track of time without external power. However, drift will still occur and increase the longer the clock is powered off. If there is an unacceptable amount of drift it is possible to connect the ethernet port on the Raspberry Pi to a router or modem with internet access. This will update the time, and thus correct and drift, as well as download any updates that may have been posted to the API including those to the "News Feed of Hope" – the most regularly updated lifeline.
