the times shown in vertical position and on standby are diferent

Are you using the "City" widget? If so, it may be set to a different city than where you live. The default is Cupertino.

One the screen where you add/edit the Standby widgets, tap the clock. It will flip over and you can change the city. Or, use a different widget.

Delete the "City" clock widget and just use one of the standard ones.

Glad it helped.
