  We construct five-dimensional non-Lorentzian Lagrangian gauge field theories
with an SU(1,3) conformal symmetry and 12 (conformal) supersymmetries. Such
theories are interesting in their own right but can arise from six-dimensional
(1,0) superconformal field theories on a conformally compactified Minkowski
spacetime. In the limit that the conformal compactification is removed the
Lagrangians we find give field theory formulations of DLCQ constructions of
six-dimensional (1,0) conformal field theories.
