This issue occurs in gov.nasa.worldwind.geom.Angle fromDMS() and fromDMdS()

The formula for converting from Degrees Minutes Seconds to Decimal Degrees uses Math.signum(degrees) to provide a positive or negative number. This causes any value less than 1 degree to become 0.0, for example 00 degrees 59 minutes 59 seconds North would become 0.0 degrees in decimal degrees as signum(0) will return 0.

Math.signum(degrees) * (Math.abs(degrees) + minutes / 60d + seconds / 3600d)
