Right now the start date determines what time gets passed in as a partition value to the run config, which might not be what people expect (like if you start a monthly schedule on the 5th of each month, we pass in a partition with the name as the month and the value as the 5th of each month). It also makes it harder to think about timezones and ensuring that we can map from tick time to partition time, although I don't *think* there's actually any bugs here.

Nice catch - this is a great fix. We should note this in the change log, because it has the potential to break some people's schedules/repositories.

| 409 | Nit: "at execute the schedule at a specified time in the day"? Same for the other messages. It might be a good idea to have a tiny example right here in these error messages, because I don't think it's entirely intuitive, but an example would immediately clarify what's wrong. Something along the lines of: For example, if you want to have a schedule run at 3:00 AM EST starting Sept 23, your schedule definition would look like:
@daily_schedule(
start_date=datetime.datetime(2020, 9, 23),
execution_time=datetime.time(3, 0),
execution_timezone="US/EST" # or whatever it is
...
):

| 409 | Sounds good, will add the example (minus the timezones since that isn't ready yet until the new scheduler is documented and stuff) | |
