Ah, so. Thanks, icu. 
Yeah, after youâve fat-fingered yourself 50 years into the past, youâre pretty much hosed - until you tap the date, get the calendar popup, which has the correct date already selected, tap the day and youâre back to the future.
A lesser peep, however, might just whimper, hit the global âbackâ button, and seek comfort elsewhere. That is a violation of the UX bill of rights and we shall not stand for it.
