Just happened onto an early twilight Zone episode starring William Shatner.
'Nick of Time' has a few things in common with City on the Edge of Forever.
The Shat finds himself in a strange town with a serious lack of crosswalks.
He and his new lady-love are torn about there destiny.
Written by Richard Matheson, this is a must see.

The lateness of the Hour is another TZ episode that would have ended better if only Kirk had intervened.
That's a great episode! It's definitely a must see!
