They are "present day" in the game, so in between quests or Arena. Your character can fluidly switch between the main storyline of Quest and do Raid or Arena without the chronology being ruined. The only parts of the game with a fixed placement in time are the Grand Gaia Chronicles, which take part in the past, and the Grand Quests, which have a set point that they occur at.
