# PetscTimeAdd

Adds the current time of day (in seconds) to the value v.

### Synopsis

    #include <petsctime.h>
    PetscTimeAdd(PetscLogDouble *v)

Not Collective

### Input Parameter

v -time counter

### Output Parameter

v -time counter (v = v + current time)

### Notes

Since the PETSc libraries incorporate timing of phases and operations, we do not ever recommend using PetscTimeAdd(). The options database command -log_summary activate PETSc library timing. See Users-Manual: Chapter 13 Profiling for more details.
