    ! *time* が変数 *name* の出力されるタイミングであれば
    ! .true. を, そうでなければ .false. を返します. 
    ! *gthstnml* が初期設定されていない場合にも .false. が返ります. 
    ! *name* に関するデータが存在しない場合にも .false. が返ります. 
    !
    ! なお, 与えられた *gthstnml* が HstNmlInfoCreate によって初期設定
    ! されていない場合, プログラムはエラーを発生させます. 
    !
    ! If *time* is the time that a variable *name* is output,
    ! .true. is returned, otherwise .false. is returned
    ! When *gthstnml* is not initialized, .false. is returned too.
    ! When data correspond to *name* is not found, .false. is returned too.
    ! 
    ! If *gthstnml* is not initialized by "HstNmlInfoCreate" yet, 
    ! error is occurred.
