I did change the tank time so it is offset by 4 hours. That way the lights are on till 11-ish. Turning off at ~7 pm was no good.
No need to bias the Apex clock, Jim. It is much easier to let the Apex run at your local time You can offset the If Sun (and If Moon) statements by as much as 10 hours (600 Minutes) before or after the time in the season table.
If Sun 600/600 Then ON/OFF/Profile
If Sun -600/-600 Then ON/OFF/Profile
