[Remind-Fans] Sun info & day|night times

[B. William]

OK, I made the changed in the ".reminders_moonsun" file:

SET $LatDeg 58
SET $LatMin 25
SET $LatSec 18

SET $LongDeg -34
SET $LongMin -37
SET $LongSec -55
FSET tomins(t) (hour(t) * 60) + minute(t)
FSET frommins(i) time(i / 60, i % 60)
FSET noon_solar(dt) sunrise(dt) + (sunset(dt)-sunrise(dt)) / 2
MSG -----
MSG Sun Rise: [sunrise()]   Set: [sunset()]
MSG    Solar noon: [noon_solar($T)]
FSET _light_len(date) MAX(SUNSET(date)-SUNRISE(date), 0)
FSET _dark_len(date) 1440-_light_len(date)
MSG  Daylight: [_light_len($T)] Minutes
MSG Moonlight: [_dark_len($T)] Minutes

What I see from that is:
-----
Sun Rise: 01:11   Set: 11.43
   Solar noon: 06:27
 Daylight: 632 Minutes
Moonlight: 808 Minutes

Something not right.
I got my lat/long info from Google maps.
I'm not the brightest bulb in the room.

Not even looking at dawn() or dusk() yet.
