This is the intro and strum throughout the song except the chorus.

G|-10--(b9)--10--(b9)-------------------------------|
D|-10--10--10--10-------------------------------|
A|-8---8---8---8--------------------------------|

It's a weird strum and I cant put it into words so listen to it and figure it out.

         G                D
Put your clock back for the winter....
   em            am         G
She asks when i'll be home again....
