When answering a question on here, I wrote a sentence similar to the following one:
I left the place I've been at previously at 3AM.
The intended meaning was that I have been at that place for a length of time, and then left it at 3AM. One user suggested that Past Perfect would be more correct here:
I left the place I had been at previously at 3AM.
On one hand, it makes sense - obviously me being at that place must have preceded me leaving that place. On the other hand, my intuitive reading of this phrase is that at some point even further in the past I had been at that place at 3AM, and at the time I'm speaking about currently I left it:
I left (the place I have been at previously) at 3AM.
I left (the place I had been at previously at 3AM).
Am I correct? Are both sentences grammatically correct? If not, is there any other way to resolve the ambiguity? Also, does the meaning change when to leave is in Present Perfect?
?I've left the place I've been at previously at 3AM.
?I've left the place I had been at previously at 3AM.
