Why would Egwene think of the same event as two different times of day? She was rescued after the Seanchan attack sometime later in the evening/night, and she would have had to wait until the exhaustion wore off before she could channel again (let alone the Forkroot), so 3am does make sense, as a time.

I am still unsure why she would think of it as "earlier that morning" at one point, and "last night" at another. A person doesn't generally change their internal narrative of their recent past... I think. It just doesn't click for me.
