I heard the following comment of Mr. Marco Rubio about Mr. Donald Trump on CBS’s “Face the Nation” in a clip in February 29th AP Radio News:

> 
> “There is never gonna be **a time where** the Republican Party rallies
> around and says you have to get out or anyone has to get out for
> purposes of rallying around Donald Trump. Donald Trump is not
> Republican Conservative. Donald Trump is trying to pull off the
> biggest scam in American political history.”

I thought I misheard “There is never gonna be a time where –“ for “There is never gonna be a time when –“ at first, because I was in understanding that time should be trailed by “when” as a relative noun or adverb.
An English Japanese dictionary at hand (Readers English Japanese Dictionary published by Kenkyusha) provides “where” singly as a relative to refer the ‘place.’

However, my lookup of the following two sources endorsed that I heard it right:

>

Is it common, at least not uncommon to use “where” after “time” as a relative?
