Reproduction of the output

Using Mono r88668 I'm getting a System.FormatException when deserializing
DateTime.MinValue. I've tested the same situation for some DateTime.Now-Values
and "DateTime.MinValue.AddTicks(1l)", which all work fine.
DateTime.MinValue, however, results in:

<?xml version="1.0" encoding="utf-16"?>
<dateTime>0001-01-01T00:00:00</dateTime>

Unhandled Exception: System.FormatException: Invalid format.
