Main Question or Discussion Point

Sorry. I know I must sound like a hick. Time is ... the 4th dimension of our conventional reference? If so, are one or more of the other dimensions posited by String Theory considered possibly to be an additional time dimension(s)?

Yes, time is one of the 4 "normal" dimensions of space-time, with space being the other 3.

The extra dimensions posited by string theory are all spacial dimensions but there is no evidence that they exist.

Only in F-Theory (total of 12 dimensions) there is an technical interpretation of one (and only one) of the extra dimensions as another form of time.
