Effect of temperature on tuning

Well, just to make sure im clear on this issue,

We've been discussing this in band class on the side and common sense seems to say that as the horn warms up or gets hot, the metal expands slightly and the horn goes flat. Likewise, coolness will contract the metal and you will go sharp.

However, i read somewhere that at least with warmth the opposite is true--that you go sharp as you get warmer.

Anyone care to shed some light on this dark subject?
