# PetscTimeAdd
Adds the current time of day (in seconds) to the value v. 
## Synopsis
```
#include <petsctime.h>
PetscErrorCode 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_view activate
PETSc library timing. See Users-Manual: ch_profiling for more details.
