The old rescheduling dialog's two options have been split into two
separate menu items, "Forget", and "Set Due Date"
For cards that are not review cards, "Set Due Date" behaves like the
old reschedule option, changing the cards into a review card, and
and setting both the interval and due date to the provided number of
days.
When "Set Due Date" is applied to a review card, it no longer resets
the card's interval. Instead, it looks at how much the provided number
of days will change the original interval, and adjusts the interval by
that amount, so that cards that are answered earlier receive a smaller
next interval, and cards that are answered after a longer delay receive
a bonus.
For example, imagine a card was answered on day 5, and given an interval
of 10 days, so it has a due date of day 15.
- if on day 10 the due date is changed to day 12 (today+2), the card
is being scheduled 3 days earlier than it was supposed to be, so the
interval will be adjusted to 7 days.
- and if on day 10 the due date is changed to day 20, the interval will
be changed from 10 days to 15 days.
There is no separate option to reset the interval of a review card, but
it can be accomplished by forgetting the card(s), and then setting the
desired due date.
Other notes:
- Added the action to the review screen as well.
- Set the shortcut to Ctrl+Shift+D, and changed the existing Delete
Tags shortcut to Ctrl+Alt+Shift+A.
- use the TimestampSecs newtype instead of raw i64s
- use FixedOffset instead of a minutes_west offset
- check localOffset each time the timing is calculated, and set it
if it's stale - even for v1.
- check for and fix missing rollover when calculating timing
- stop explicitly passing localOffset in the sync/start call
