Yes, "out of the price specs" because clearly it would cost an extra $10,000 at least to write a 4 line program that would allow the software to do timelapses. Somehow the third parties manage to do it for like $2 a unit. Or hell, I can go to Walmart and get a little blinky ball for $1 probably that has timer circuits in it, in addition to the actual hardware.
I'm right there with you man. The fact that all DSLRs do not include this is just flat out terrible design at best, or an intentional sketchy incentive to upgrade and/or buy peripherals at worst. There's really no excuse for that.
Sort of like how they cut off exposure compensation at 4 or 5 on some cameras. Why is it not infinite on every camera? etc. They just cripple some things on purpose, for some business reason that I guess probably makes sense at some level, but not for our best interests.
