Tense logic without tense operators,
Mathematical Logic Quarterly 42, 1996, 145 - 171.
Abstract: It is proved that any finitely axiomatizable temporal logic with the operators ALWAYS IN THE FUTURE and ALWAYS IN THE PAST and containing the left- and right-linearity axioms is decidable. An inspection of the proof should show that they are NP-complete.

The finite model property in tense logic,
Journal of Symbolic Logic 60, 1995, 757 - 774.
Abstract: Suppose L is a modal logic determined by a class of transitive frames which is closed under cofinal subframes. Denote by LP the axiomatic extension of L by means of the past-time operator. It is proved that LP has the finite model property if and only if the class of frames validating L is first-order definable.
