Subject: faces/clock: refactor low power tick function
X-Git-Url: https://git.earman.xyz/?a=commitdiff_plain;h=1d79930ab79835222e76567f520a53379ad0546b;p=sensor-watch.git

faces/clock: refactor low power tick function

Simplifies the code by defining dedicated functions
and separating the case from the main ones.

Also use the snprintf function since the buffer size is known.
