What is the function of 已 in 好像她已出去好几天了。 What is the purpose of 已 in the following sentence？


  好像她已出去好几天了。


The English translation given is:


  It looks as if she's gone away for a few days.


Or is this an incorrect-character, supposed to be something else?
Here 已 has the same meaning as 已经 and means already. When speaking one would normally use 已经, but in written documents 已 can be found.

I would translate 好像她已出去好几天了 as "It seems she's already been gone for some days".
