Weekly Event Quest Reset Time: Why?

They reset at 4 server time. And this is three hours before most everything else resets, including the start of the new weekly event, so what gives? I legitimately do not understand why this is an outlier and to this extent. And it’s quite easy to forget it’s the case unless you’ve been burned a few times. Does anyone know?

Obviously I ask because losing your quest at 9/10 skirmishes done is really dispiriting. I don’t know why it has to be THREE hours earlier when another arbitrary number like 2 would have been fine for me and other procrastinators
