+The DEFAULT constraint specifies a default value to use when doing an INSERT.
+The value may be NULL, a string constant, a number, or one of the special
+case-independant keywords CURRENT_TIME, CURRENT_DATE or CURRENT_TIMESTAMP.
+If the value is NULL, a string constant or number, it is literally inserted
+into the column whenever an INSERT statement that does not specify a value
+for the column is executed. If the value is CURRENT_TIME, CURRENT_DATE or
+CURRENT_TIMESTAMP, then the current UTC date and/or time is inserted into
+the columns. For CURRENT_TIME, the format is HH:MM:SS. For CURRENT_DATE, 
+YYYY-MM-DD. The format for CURRENT_TIMESTAMP is "YYYY-MM-DD HH:MM:SS".
