Time output and suppression of time settings

With the parameter "S7_Uhr_Stellen", a setting for the S7 clock can be suppressed if
only the time information of the DCF77 signal shall be provided to the application
program for an own further processing.
The output "Impuls_Minute" changes its value exactly on the minute beginning when
the function block is synchronous and the last time telegram was correctly decoded.
The time determined by the function block is then available for further procedure at
the output "Zeit_Ausgang".
