The SDI allows for configuration of the user interface and computational properties through the use of -d flags.
This flag allows the user to define multiple events per year, or an event that spans multiple years. Events are defined through the presence of null data in the data record for the primary location.
This flag will prevent sdi from shifting data from the originally stated date and time in the sdi input data.
This flag will prevent sdi from the sdi input data. Use with caution
