Oops, I found an error that is pretty important.

The following two lines make the Earth turn the wrong way

> rot = (rot[2]+rot[3]/60.+rot[4]/3600.)/24.*360 - 270
> ENDIF ELSE rot = time/24. * 360 - 270

replace them with:
rot = -(rot[2]+rot[3]/60.+rot[4]/3600.)/24.*360 + 90
ENDIF ELSE rot = -time/24. * 360 + 90

for an Earth that turns the correct direction.
