nope, i disagree with all previous posts
i'd say go with the lrtimelapse way. it's lightroom + lrtimelapse, a free program (
http://lrtimelapse.com/), but you have much more workability than just lightroom because you can ramp the settings between keyframes, so if you do a shot from day to night, you can set the settings for when it's day as well as at night, then it will automatically ramp between the two for a very smooth looking timelapse where you can maximize your ability to get the most out of your images. also, you can use "deflicker" which will remove any flickers from adjusting exposures, which, in turn, enables you to also shoot timelapses in modes like "P", not just "M".
this summer i used lrtimelapse and lightroom together and they were damn helpful:
