[Remind-Fans] sun moon data

[Sector11]

I have a friend in Germany using remind and he says he is getting the wrong
sun data with this file:
=========================================
## remind -q -r ~/.reminders.sun.v
##  http://www.geonames.org/search.html?q=Lichtenstein+Sa.&country=DE

## Eastern
SET $LatDeg -12
SET $LatMin -37
SET $LatSec -48
## Northern
SET $LongDeg 50
SET $LongMin 45
SET $LongSec 23

##  SUN STUFF ##

FSET tomins(t) (hour(t) * 60) + minute(t)
FSET frommins(i) time(i / 60, i % 60)
FSET noon_solar(dt)  + (sunset(dt)-sunrise(dt)) / 2
FSET _light_len(date) MAX(SUNSET(date)-SUNRISE(date), 0)
FSET _dark_len(date) 1440-_light_len(date)

Is there something configured wrong here??

I get:

   $ remind -q -r ~/.reminders.sun.v
