Since the PETSc libraries incorporate timing of phases and operations, we do not every recommend using PetscTimeSubtract() The options database command -log_summary activates PETSc library timing. See Users-Manual: Chapter 12 Profiling for more details, also see PetscLogStageRegister(), PetscLogEventRegister(), PetscLogEventBegin(), PetscLogEventEnd() for how to register stages and events in application codes.
