I was interested in finding out how common the first one was, so I did a corpus search. I'll post the results -- perhaps someone will find them interesting.
My queries were:
1) since that [user:list] [p*]|[n*] have|has
2) from that [user:list] [p*]|[n*] have|has

[user:list] means "any of the words from word list 'list' defined by user 'user'". My list contained the following words (based on previous searches):
[p*]|[n*] means "any pronoun or any noun".
have|has means "the word 'have' or the word 'has'".
