# 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 `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);
