public class DateAndFlags extends DataStructureImpl
A six-byte Date and 2 bytes of flags, since a Date won't encroach on the top two bytes until the year 10889. The flag format is not specified here. The bits may be used in an application-specific manner. The application should be designed so that a flags value of 0 is the default, for compatibility with an 8-byte Date. See extending class net.i2p.client.SendMessageOptions for more info. If we really need some more bits we could use the first few bits of the third byte.

      out - stream to write to
      Throws:
      DataFormatException - if the data was incomplete or not yet ready to be written
      IOException - if there was a problem writing to the stream
