The snippet I posted requires only that pyephem be installed. Everything
else comes with generic WeeWX. The snippet can be included anywhere.
I should note that my cut-and-paste wasn't chosen very well. The Cheetah
logic includes a closing "#end if", but not the opening "#if". The correct
snippet would look like:
## If extended almanac information is available, calculate change in daylight.
#if $almanac.hasExtras
## For the change in daylight, pick a string to indicate whether it is more or
## less than yesterday:
#set $sun_visible_change = $almanac.sun.visible_change
#if $sun_visible_change.raw < 0
#set $change_str = $gettext("less than yesterday")
#else
#set $change_str = $gettext("more than yesterday")
#end if
#end if
The HTML is as before.
