Logs should be in local timezone (and seem to have too many new lines?)

Description

I think it would be simpler if logs were in my local (machine) timezone. I can't think of a reason to have them in GMT. Also there seems to be an extra new line character?

Probably something like https://github.com/winstonjs/winston#custom-log-format for the fixing timestamp.

The extra newline is an artifact of the mismatch between child process stdout being piped to the parent, and the winston logger used by the Emulator. I haven't prioritized the newline enough to spend the time to dig into it further to find the right fix.
