A simple "date (DD/MM/YYYY)" or similar format above a text field is a blessing these days, but I'll take anything over a date picker. A good date picker would let the year drop down somewhere, show calendar view, and allow text input of the date. That's the minimum requirements, a month drop down would be nice too. Sometimes I run into date pickers that have some unintuitive way to page years, one click at a time of course, and while I dislike that, at least I can move back by a year, it doesnt ruin my day. Imagine someone deciding that to input the exact time of something you'd select a drop down containing Unix timestamps, one option for each second, that's probably the only thing I can think of that would be more frustrating and senseless than the current state of affairs, and even then perhaps not because at least it's a dropdown you can scroll on. Literally a scrolling dropdown of all dates back to 01/01/1900 would be a superior UX to the current common date picker design.
