_{4}(x,y,z,ict) -> Minkowski Metric

The two "metrics" are confusing me. I understand that both systems were formed so that all 4 dimensions have the same units. However, I don't know which one to use and I don't really understand how each metric system was formed (the thought process behind their creation). The Minkowski metric is especially confusing for me due to the imaginary "ict" factor. I think the differences in the metric system also has to do with the signs of each term. For example i see both these notations floating around (-+++) and (+---). Any help would be greatly appreciated.
