In SQL, can we always write an inner join statement as a main query and subquery?

For example,

 select * from gifts g where g.giftID in (select giftID from sentGifts);

can do a join and show the gifts sent in the sentGifts table, but it won't be able to show the sentTime because that is inside the subquery?
