stamp with date on my passport

[onetime]

I came over today and got searched/interrogated but let through. I let them know I was staying til at least the 13th but I just noticed my passport was stamped and has jan 11th written below the stamp. Should I be worried about staying past the 11th? I was never informed of anything by the immigration officer or anyone else, I just happened to look in the back of my passport and saw this on my own.

You probably pissed the Port of Entry officer. That's 6 days allowed stay!!!! You would have overstayed if you stayed past Jan 11, 2012 and you're probably flagged on the system. Anyway, it won't matter much if you don't intend to come back to Canada. From what country are you?

if you overstay they will not let you in again that easy
And what did you do to make that "stampman" so pissed at you ?
