# TSMonitorWallClockTime

Monitor wall-clock time, KSP iterations, and SNES iterations per step.

## Synopsis

    #include "petscts.h"
    PetscErrorCode TSMonitorWallClockTime(TS ts, PetscInt step, PetscReal ptime, Vec v, PetscViewerAndFormat *vf)

## Input Parameters

- ts - the `TS` context

- step - iteration number (after the final time step the monitor routine may be called with a step of -1, this indicates the solution has been interpolated to this time)

- ptime - current time

- v - current solution

- vf - the viewer and format

## Options Database Key

- -ts_monitor_wall_clock_time - Monitor wall-clock time, KSP iterations, and SNES iterations per step.

## Note

This is not called directly by users, rather one calls `TSMonitorSetFromOptions()`, with this function and `TSMonitorWallClockTimeSetUp()` as arguments, to cause the monitor to be used during the `TS` integration.
