Updraft Schedule

Describe when something should happen, and let the extension work out the cron expression — including what to do about daylight saving.

Cron expressions are a poor interface for human intent. They are terse, they have three incompatible dialects across AWS services, and they have no concept of a time zone at all. The result is that “run at 3am Toronto time” becomes a UTC field string that is correct for five months of the year.

These types take the intent and emit the expression.
