I come in about 7 and leave at about 7. The actual time I'm on the PCA site is very small although, I agree, it may seem a lot. I tend to pop in for a few minutes/seconds several times a day and the PCA line is usually always open.
I am by nature an "early bird" and, for as long as I can remember, I have got up at about 5:00 am throughout the year. I am also an early sleeper.
