BloombergLP::bdlt::Datetime::addTime

Add the specified number of hours, and the optionally specified number of minutes, seconds, milliseconds, and microseconds to the value of this object, adjusting the "date" part of this object accordingly. Unspecified trailing optional parameters default to 0. Return a reference providing modifiable access to this object. If 24 == hour() on entry, set the hour attribute to 0 before performing the addition. The behavior is undefined unless the resulting value is in the valid range for a Datetime object. Note that each argument independently may be positive, negative, or 0.
