Effect of temperature on carbonation time

I know that cold liquids absorb gas better, so is it fair to say that if my beer is at 30 degrees F it will carbonate more quickly than if it is at 40 deg F. I am going to keg my imperial stout within the next few days. The drinking temperature for it according to what I read is 55 degrees. If I carbonate at 30 degrees will it carbonate faster and then I raise the temp to 55? Or does it not matter because I should be adjusting the pressure based on the temperature?

Colder. It will dissolve CO2 more readily and at less required pressure. With that said it doesn’t really matter as I would give it 2 weeks for the CO2 to hydrate. Therefore 30° or 40°, doesn’t matter.
