Kon: Here, both sound more or less correct in that we do hear them, but as Ray says, they don't sound very good.
Ray: They're not ambiguous in this case. But when you have a sentence like“We've raised $300 as of last Saturday", it can mean“up until last Saturday" or “since last Saturday". “As at" is not so bad as“as of”, but I still can't see the need for it.
Barb: There may be some regional difference, then, Ray. If someone said“We've raised $300 as of last Saturday," for me, that would only mean that“The last time I checked was Saturday, and on that day, we had raised $300, but it may be more than that now. ”
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American). English.
Ray: Here it tends to mean 'since '： “ As of our last conversation, your work hasn't improved at all! ”
鉴于as of使用的混乱，有时甚至表达相反的意思（up until与since)， A Dictionary of Modem Legal Usage (2nd Edition, Bryan A. Gamer, Law Press, China)在as of词条中指出：
As of should be used with caution. Originally an Americanism, the phrase frequently signifies the effective legal date of a document, as when the document is backdated or when the parties sign at different times. When such a nuance is not intended, as of is the wrong phrase. E. g. , it is often inferior to on: “ The plaintiff's employment with the defendant ended as of [ read on] September 30. ”
因此，我的建议是，必要时可用as of表达as from之意；否则要尽量避免使用as of，而是使用意思更清楚的on, at, up until等词。最后，为便于理解of与from的关系，请大家看看of的词源：
Middle English, off, of, from Old English, adverb & preposition；akin to Old High German aba off, away, Latin about from, away, Greek apo ( The Merriam-Webster's Collegiate Dictionary)
