While advocating for a year's notice or any change, can I advocate that any
release of timedata is also a year in advance of that change.    Airlines
take advance bookings up to 360 days of first outbound travel and so a late
released change can mean late rescheduling of flights, updating of tickets,
potentially rebooking of tickets where connections no longer connect.

In the past releases have been considered not urgent, but this change is
much more significant due the size of the market being impacted.
