I have always had a good sense of time - before the abuse, after the abuse and after recovering memories of the abuse - in that I have never worn a watch and, if asked, could usually tell you the time with pretty good accuracy.
However, ever since the abuse I have lost chunks of time to blackouts and flashbacks. Coming out of them, I realise that time has passed and can even have a pretty good guess at how much but, for a while, time doesn't exist (more so with blackouts than flashbacks as I tend to experience my flashbacks as if the past is overlaid on the present, both existing at once, so there is some sense of present time even when I am reliving a past time).
When I first started to recover my memories and was diagnosed with PTSD, I had a very strange sense of time. I still knew the time quite accurately without looking at a clock, but I didn't always feel part of it. My body wasn't quite "real". I was aware of the passage of time, but only because of all the cues that this body was aware of. It was an odd feeling which is less frequent now.
I have also found that time seems to have passed very quickly. The past two months have felt more like two weeks. They say time flies when you're having fun, so I would have expected the opposite. My time certainly hasn't been fun.
Perhaps following on from this, I find that things happen too quickly for me now. I need to take much longer to complete a task than I used to. I just can't take in information as fast as I used to. I even walk slower.
And then there's the forgetfulness. I guess that can be seen as a failing in my sense of time.
