The ship ride to/from Kugane is supposed to be about 2 months, as per the lore book.
But as I'm sure Sounsyy stated, stop trying to put a marked date on the game's timeline. Time bubbles don't work that way.
Instead, I'd recommend the fuzzy timeline method. Rather than referring to something with a hard date, refer to it within the general happening of things in the MQS/story. "This takes place around the time the WoL would have been doing _____ ." Not only do you achieve the same same thing, you aren't going to be hindered by people who've played the game for different lengths of time and have to either expand or squash their timelines to sync up.
