dcdatetime_gt_ff()

logical function dcdatetime_gt_ff	(	type(dc_difftime), intent(in)	diff1,
		type(dc_difftime), intent(in)	diff2
	)

2つの DC_DIFFTIME 変数の比較 (>)

2 つの引数の日時差を比較します. 1 つ目の引数に格納される日時差が 2 つ目の引数に格納される日時差 よりも大きい場合, .true. が返ります.

Parameters

[in]	diff1	比較する1番目の日時差
[in]	diff2	比較する2番目の日時差

Returns

diff1 > diff2 の場合 .true., それ以外は .false.
