+ * History is a special case, because we don't want Updates or Deletes... Too likely to mess up history.\r
+ * \r
+ * 9-9-2013 - Found a problem with using "Prepare". You cannot prepare anything with a "now()" in it, as\r
+ * it is evaluated once during the prepare, and kept. That renders any use of "now()" pointless. Therefore\r
+ * the Create function needs to be run fresh everytime.\r
