Extra second prior to Dec 13, 1901

>>> Pendulum(1901, 12, 13, 0, 0, 9, 555555, 'US/Central')
<Pendulum [1901-12-13T00:00:10.555555-06:00]>

Notice the 9 seconds became 10 seconds.

Dates after December 13, 1901 don't have this issue:

>>> Pendulum(1901, 12, 14, 0, 0, 9, 555555, 'US/Central')
<Pendulum [1901-12-14T00:00:09.555555-06:00]>

This issue seems to be dependent upon the microseconds term:

>>> Pendulum(1901, 12, 13, 0, 0, 9, 0, 'US/Central')
<Pendulum [1901-12-13T00:00:09-06:00]>

It also seems to be dependent upon the time zone:

>>> Pendulum(1901, 12, 13, 0, 0, 9, 555555, 'UTC')
<Pendulum [1901-12-13T00:00:09.555555+00:00]>

December 13, 1901 seems to correspond with the minimum value of a 32-bit signed integer:

Thanks for reporting this.

This is a weird bug indeed. I am not sure where it comes from.

I will investigate and get back to you.

This is fixed in commit c0d37bd.

It will land in the next bugfix release.
