Add microseconds if the result remains a valid datetime.
Add the specified number of microseconds to the value of this object, adjusting the "date" part of the object accordingly, if the resulting value is in the valid range for a Datetime object. If 24 == hour() on entry, set the hour attribute to 0 before performing the addition. Return 0 on success, and a non-zero value (with no effect) otherwise. Note that microseconds may be positive, negative, or 0.
