Lein, it will be a long explanation, sorry for that.
It has been already discussed (in Ukranian) that this request contains a word nobody knows. I made my research via google and every other source of this phrase is identical to the one posted here.
So actually this request cannot be translated without guessing (as far as my knowledge of Ukranian allows me to judge).
Apart from this I don't agree with the last two sentences. Felicitas wrote about the second sentence and I agree with her that it's more logical (though it's guesswork as we can't tell).
The last sentence I believe should be: "Daily at 21:00 Lviv time" as in "Event starts daily at 9:00 PM passific time".
