Currency exchange at a specific date and time

Millions,

Anyone know of a website wherein you can get the currency exchange at a specific date and time. Something like “I need to know the Canadian dollar to US dollar rate on November 12th at 1:35 p.m. and I need to know it now.” Something like that.

This site seems to have what you’re looking for. I’m not sure if you can narrow it down to the hour/minute, though.

This one works nicely.

Both are more than adequite. Much obliged.
