The value of this constant is 1/1/0001 12:00:00 AM +00:00.

The DateTimeOffset.MinValue property is used to determine whether the value of a new DateTimeOffset object or the DateTimeOffset value returned by an arithmetic operation is the same as or later than this minimum range value. If it is not, the method throws an ArgumentOutOfRangeException. Any DateTimeOffset value is converted to Coordinated Universal Time (UTC) before the method performs the comparison with DateTimeOffset.MinValue. This means that a DateTimeOffset value whose date and time are close to the minimum range, but whose offset is positive, may throw an exception. For example, the value 1/1/0001 1:00:00 AM +02:00 is out of range because it is one hour earlier than DateTimeOffset.MinValue when it is converted to UTC.
