Your graphs.conf looks correct, but the error is not related to
day_ago_to_now, it looks like day_ago_to_now is being skipped for some
reason.
Take a backup of graphs.conf, then try this as your only item in
graphs.conf?
[timetestchart]
title = Time Test Chart
show_button = true
button_text = Time Test Chart
gapsize = 300
[[chart1]]
title = Temperature
time_length = day_ago_to_now
time_ago = 1
start_at_midnight = true
#aggregate_type = max
#aggregate_interval = 86400 # 1 day
gapsize = 86400
[[[outTemp]]]
zIndex = 1
name = Temperature
[[[windchill]]]
[[[heatindex]]]
[[[dewpoint]]]
