I have a DLM for UNIX which implements IGRF and the NSSCDC GEOCGM library.
One of the parameters caclulated by GEOCGM is the UT of MLT midnight.
See http://nssdc.gsfc.nasa.gov/space/cgm/cgm.html for details.

If you are interested I could probably package this up for you with some
basic installation instructions.
