# TSClone
This function clones a time step 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 ARKIMEX 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);
