4:37.86, but I was interrupted by two phone calls, and got the quote wrong, although my answer was a valid English sentence, just not a sensible one. Not that this one is sensible.
I googled the quote and the translation I happened on inserts a word after TEHP giving the following:
IP LIF IWM W LIO YF TEHP [DFC] KWS QPWC WTXFMY WSO IFL.-—SEPYJMKIP
Took me 1:25 to solve it. Based on that, you have solved it within 0:62 secs.
I understand this quote now as much as I did when I was forced to study the dude back in college. Maybe the wrong teacher taught it. What a mental nightmare it was for me.
