  In non-centrosymmetric superconductors the pair potential has both
even-parity singlet and odd-parity triplet components. If time-reversal
symmetry is broken, the superconducting phase of these components is not the
same, for example in anapole superconductors. In this paper it is shown that
breaking time-reversal symmetry by a phase difference between the two
components significantly alters both the density of states and the conductance
in s+helical p-wave superconductors. The density of states and conductance in
s+chiral p-wave superconductors are less influenced by adding a phase
difference because time reversal symmetry is already broken in the s+p-wave
superconductor. The Tanaka-Nazarov boundary conditions are extended to 3D
superconductors, allowing to investigate a greater variety of superconductors,
such as B-W superconductors, in which the direction of the d-vector is parallel
to the direction of momentum. The results are important for the determination
of pair potentials in potentially time-reversal symmetry broken
non-centrosymmetric superconductors.
