delay differential equation or retarded differential equation is the 
correct term. 
hairer , norsett and wanner treat it in chapter II.15 of
"solving ordinary differential equations I" (springer publisher).
they also have code (retard.f) at 
 http://www.unige.ch/math/folks/hairer/

hope this helps
