Python does not guarentee that the time module will function outside of the range Epoch -> 2038.

I propose this patch, although it doesn't solve the real problem of DateTime being less than useful in this case:

When I try to format a DateTime object older than 1970/1/1, using strftime(), I receive an:

Error Type: IOError
Error Value: [Errno 22] Invalid argument
