	xSetGmt		: BOOL;
	xSetCet		: BOOL;
	rtsResult	: SysTypes.RTS_IEC_RESULT;
	diReturn	: DINT;
END_VAR



Implementation

IF xSetGmt THEN
	xSetGmt	:= FALSE;
	diReturn := Sysprocess.SysProcessExecuteCommand(pszComand := sCmdGmt, ADR(rtsResult));
END_IF

IF xSetCet THEN
	xSetCet	:= FALSE;
	diReturn := Sysprocess.SysProcessExecuteCommand(pszComand := sCmdCet, ADR(rtsResult));
