Riding MVJ's excellent F_TABLE_DATE function, I often use this view for current date and time information.

SELECT		CURRENT_TIMESTAMP AS Now,
		DATEADD(MINUTE, DATEDIFF(MINUTE, 0.00069445, CURRENT_TIMESTAMP), 0) AS previousMinute,
		DATEADD(MINUTE, DATEDIFF(MINUTE, 0, CURRENT_TIMESTAMP), 0) AS thisMinute,
		DATEADD(MINUTE, DATEDIFF(MINUTE, 0, CURRENT_TIMESTAMP), 0.00069445) AS nextMinute,
		DATEADD(HOUR, DATEDIFF(HOUR, 0.0416667, CURRENT_TIMESTAMP), 0) AS previousHour,
		DATEADD(HOUR, DATEDIFF(HOUR, 0, CURRENT_TIMESTAMP), 0) AS thisHour,
		DATEADD(HOUR, DATEDIFF(HOUR, 0, CURRENT_TIMESTAMP), 0.0416667) AS nextHour,
		DATEADD(DAY, DATEDIFF(DAY, 1, CURRENT_TIMESTAMP), 0) AS previousDay,
		DATEADD(DAY, DATEDIFF(DAY, 0, CURRENT_TIMESTAMP), 0) AS thisDay,
		DATEADD(DAY, DATEDIFF(DAY, 0, CURRENT_TIMESTAMP), 1) AS nextDay,
		DATEADD(WEEK, DATEDIFF(WEEK, 7, CURRENT_TIMESTAMP), 0) AS previousWeek,
		DATEADD(WEEK, DATEDIFF(WEEK, 0, CURRENT_TIMESTAMP), 0) AS thisWeek,
		DATEADD(WEEK, DATEDIFF(WEEK, 0, CURRENT_TIMESTAMP), 7) AS nextWeek,
		DATEADD(MONTH, DATEDIFF(MONTH, 31, CURRENT_TIMESTAMP), 0) AS previousMonth,
		DATEADD(MONTH, DATEDIFF(MONTH, 0, CURRENT_TIMESTAMP), 0) AS thisMonth,
		DATEADD(MONTH, DATEDIFF(MONTH, -1, CURRENT_TIMESTAMP), 0) AS nextMonth,
		DATEADD(QUARTER, DATEDIFF(QUARTER, 92, CURRENT_TIMESTAMP), 0) AS previousQuarter,
		DATEADD(QUARTER, DATEDIFF(QUARTER, 0, CURRENT_TIMESTAMP), 0) AS thisQuarter,
		DATEADD(QUARTER, DATEDIFF(QUARTER, -1, CURRENT_TIMESTAMP), 0) AS nextQuarter,
		DATEADD(YEAR, DATEDIFF(YEAR, 365, CURRENT_TIMESTAMP), 0) AS previousYear,
		DATEADD(YEAR, DATEDIFF(YEAR, 0, CURRENT_TIMESTAMP), 0) AS thisYear,
		DATEADD(YEAR, DATEDIFF(YEAR, -1, CURRENT_TIMESTAMP), 0) AS nextYear

For example, If I want this weeks data I just join against this view and use

WHERE	DtCol >= thisWeek
	AND DtCol < nextWeek

Or previous months data

WHERE	DtCol >= previousMonth
	AND DtCol < thisMonth

EDIT: Faster week calculations.

Sorry, but i don't see any references to the F_TABLE_DATE used in your view here.

The text "here" is a link to Michaels function.

I will edit the original post to avoid the confusion in the future.
