Timestamp Out of Range Exception

[ye]

The timestamp that's stored in Trac 0.12.2 is in microseconds not seconds. So it's necessary to convert it into seconds by dividing 100000.

$ ./trac2pivotal.py trac.db pline-tractickets.csv
Reading "trac.db", writing "pline-tractickets-*.csv".

ValueError: year is out of range

Will send a pull request for the fix.
