I agree. I'd wager most programmers don't need to actually worry about calendars, but most occasionally need to worry about time. Just use a library and read the docs for what to expect to happen when you do something like getCurrentTime. What is the resolution, does it monotonically increase, etc. If you actually need to worry about calendars and user input, you have my sympathy.
