-  Check datetime value for validity according to flags.
-
-  SYNOPSIS
-    check_date()
-      ltime          Date to check.
-      not_zero_date  ltime is not the zero date
-      flags          flags to check
-      was_cut        set to 2 if value was truncated.
-		     NOTE: This is not touched if value was not truncated
-  NOTES
-    Here we assume that year and month is ok !

+  @param[in]  ltime          Date to check.
+  @param[in]  not_zero_date  ltime is not the zero date
+  @param[in]  flags          flags to check

+  @param[out] was_cut        set to 2 if value was invalid according to flags.
+                             (Feb 29 in non-leap etc.)  This remains unchanged
+                             if value is not invalid.
+
+  @details Here we assume that year and month is ok!
     If month is 0 we allow any date. (This only happens if we allow zero
     date parts in str_to_datetime())
     Disallow dates with zero year and non-zero month and/or day.
