Because you are printing the timestamp as a signed value ;-)
Note that 2^33 - 3590 = 8589927402 + 3600, so everything seems
to be ok. If you do not like the negative value, just use "%Lu"
(I assume you are using "%Ld"?).
That said, I repeat that I do not know if av_read_frame() is
supposed to return values on 33bit, or if some code in utils.c
is supposed to convert them to 64bit...
