Great idea!
Do you know that you can also enter your latitude and longitude in Setup, Sun?
Quote:
| This Setup area allows you to define your latitude and longitude which is used in the sunrise, sunset, and civil twilight calculations. You can select your state and city, or manually enter your latitude and longitude. You must also manually select whether or not you observe daylight savings time in your area. |
|
|
You can then check DAWN, SUNRISE, SUNSET, and DUSK.
Also, here's a way to reduce the code a bit...
Code:
| Case( month( today())when 4 to 9 then ph_createtimedevent( 0,"<YOUR MACRO>", ph_relativedatetime( today(),90)) else ph_macro( "<YOUR MACRO>")) |

sure, i've got the sun tab setup and daylight savings too, but I have found out that here, especially in the sommer, it is not nessecary to have the lights turned on at sunset, mostly it there is daylight enough for at least an hour... and in winter it is just the other way around... I tried at first using your reduced code but for a reason unknown to me I got an error when executing... Also when I was programming it, it wasn't as early as i thought

Not directly related, but somewhat. Are DAWN, SUNRISE, SUNSET and DUSK PH variables that can be referenced? I have a couple of uses for these if so. I didn't know if they were just internal or could be addressed directly in a macro or formula. (Ok, probably a stupid question, but i'm asking it anyway!

Yup. From the manual...
Quote:
[DAWN] This variable returns the start of civil twilight as the number of seconds past midnight.
[DUSK] This variable returns the end of civil twilight as number of seconds past midnight.
[SUNRISE] This variable returns the time of sunrise as the number of seconds past midnight.
[SUNSET] This variable returns the time of sunset as the number of seconds past midnight. |

I had a question once when I was member of Fido-Net and all I got was: "RTFM!"
Since then the first thing I do is actually read the .. manual

I try not to say RTFM until the second question that can be answered by doing it!
