The first two, along with :All You Zombies", are consistent and take what I call the space-time view of time travel; if you travel into the past, that's part of your history and you will do whatever history records that you did. Attempts to change that are also part of your history.
That theme occurs in Greek Mythology: "a tragic end for a loyal son who loved his mother."
The stories in which the actions of a time traveller spin off another branch of the Universe are on shakier grounds; ask me about them when we have a viable Quantum Gravity.
Some of the others that you mention, e.g., clocks running inconsistently, are just carelessness or perhaps C2H5OH. They play the Devil with my willing suspension of disbelief.
