When’s “day time” end for you? Noon server time? Two? Four? I ask because with a more specific time, I can give more useful feedback and keep an eye out for stuff that works for you.
Otherwise, I can just tell you that while RP hubs will be slow compared to 5-9pm server time, but there will always be someone available for walk-ups. Oh, and I’d give you a general list of RP events that may or may-not meet your criteria… which I’ll do anyway!

There’s an RP-PvP campaign running too.
