Provia and Acros will both go out to 2 minutes with no compensation. That makes cameras that can time out that far on AE very useful, if the scene will not fool the meter, as can happen. Even if it is fooled, one nice thing about night exposures is that they are more subjective. A range of exposures from mostly dark to full daylight will all work, depending on what is wanted. An LX will attempt to make a night scene look like daylight, and will go all night to do it, if the batteries hold out.
I like night scenes to look like night, so less exposure is generally desirable. Using the compensation dial helps accomplish this, as do reciprocity characteristics, if they come into play. I seldom concern myself with the color shift, though I will compensate according to the manufacturer's directions sometimes.
