Mixed connective tissue disease (MCTD) is a rare autoimmune disorder. An autoimmune disorder is one in which the immune system mistakenly views the bodyâs own tissues as âinvadersâ and attacks them.ixed connective tissue disease has features of three other connective tissue diseases: 1  Systemic lupus erythematosus (SLE) â An inflammatory disease that can affect many different organs. 2  Symptoms include fever, fatigue, joint pains, weakness, and skin rashes on the face, neck, and upper body.
Almost all of the US state of Arizona does not use Daylight Saving Time (DST), and uses the time zone Mountain Standard Time (MST) all year.
In Indiana, where part of the state observes DST and part does not, farmers have opposed a move to DST. Farmers, who must wake with the sun no matter what time their clock says, are greatly inconvenienced by having to change their schedule in order to sell their crops to people who observe daylight saving time.
