# TSClone

This function clones a time step `TS` object.

## Synopsis

    #include "petscts.h"
    PetscErrorCode TSClone(TS tsin, TS *tsout)

Collective

## Input Parameter

- tsin - The input `TS`

## Output Parameter

- tsout - The output `TS` (cloned)

## Notes

This function is used to create a clone of a `TS` object. It is used in `TSARKIMEX` for initializing the slope for first stage explicit methods. It will likely be replaced in the future with a mechanism of switching methods on the fly.

When using `TSDestroy()` on a clone the user has to first reset the correct `TS` reference in the embedded `SNES` object: e.g., by running

     SNES snes_dup = NULL;
     TSGetSNES(ts,&snes_dup);
     TSSetSNES(ts,snes_dup);
