Yes - about 7 minutes. But - I wish it could be like that Twilight Zone episode where the Sun goes and the guy (Merideth Burgess??) figures it out while it is still night in Manhatten. He has the rest of the night to set things right - and finally gets the gumption to ask the girl out on a date and they spend the evening together before the dawn brings them around to the exploding Sun.
Alas - like most catastrophic things - you won’t have time to prepare and it will be in an instant. So, remember to give your loved ones an extra hug and a kiss each time.
I just watched that episode not too long ago!
But I think it The Outer Limits?
