+When an author or committer date field is focused, press `Enter` to open the date/time picker. Arrow keys adjust the day and hour, `PgUp`/`PgDn` adjust the month, `+`/`-` adjust by five minutes, and `H`/`L` adjust the year. Use `t` for now, `z` for local time, `u` for UTC, `Enter` to save, or `Esc` to cancel. `Ctrl+T` remains a quick shortcut for setting the focused date to now.
