the building blocks of this would include:

datediff(day,startDate,endDate)
datediff(hour,startDate,endDate)
datediff(minute,startDate,endDate)

What happens after '59 minutes ago'?
for example, 78 minutes, how is this to be displayed?
or, 27 hours?

I'd suggest some more definition of the requirement may be required

You can do this in PHP as well, please check the following:

http://php.net/manual/en/function.strtotime.php

and in MSSQL, see the following thread

I used this .but still its not working

declare @DateValue datetime
select @DateValue ='2013-05-14 15:29:55.090'

SELECT  CASE
          WHEN @DateValue-GETDATE() >= 1 THEN CAST(DATEPART(dy, @DateValue-GETDATE()) AS varchar) + ' day(s) remaining'
          WHEN @DateValue-GETDATE() >= 0 THEN CAST(DATEPART(hh, @DateValue-GETDATE()) AS varchar) + ' hour(s) remaining'
          /*Note, it's convenient to switch around for negatives*/
          WHEN GETDATE()-@DateValue <= '00:59' THEN CAST(DATEPART(mi, GETDATE()-@DateValue) AS varchar) + ' minutes(s) overdue'
          WHEN GETDATE()-@DateValue <= 1 THEN CAST(DATEPART(hh, GETDATE()-@DateValue) AS varchar) + ' hours(s) overdue'
        ELSE
          CONVERT(varchar, @DateValue-GETDATE(), 121)
        END AS Time_Scale

maybe this would help?
DECLARE	@START_DATE	DATETIME
DECLARE	@END_DATE	DATETIME
SET		@START_DATE = '2013-05-01 09:00:00'
SET		@END_DATE =   '2013-05-03 11:14:22'

SELECT
  CONVERT(varchar(6), DATEDIFF(day, @START_DATE, @END_DATE))
+ ' days '
+ CONVERT(varchar(6), (DATEDIFF(second, @START_DATE, @END_DATE)/ 3600) % 24)
+ ' hours '
+ RIGHT('0' + CONVERT(varchar(2), (DATEDIFF(second, @START_DATE, @END_DATE) % 3600) / 60), 2)
+ ' minutes ago'
 AS 'time ago'

so, when dealing with both future and past possibilities, then the datediff calculations need a reversal of dates, like this:
DECLARE	@START_DATE	DATETIME
DECLARE	@END_DATE	DATETIME
SET		@end_DATE = '2013-05-01 09:00:00'
SET		@start_DATE =   '2013-05-03 11:14:22'

SELECT
case when @start_date <= @end_date then
  CONVERT(varchar(6), DATEDIFF(day, @START_DATE, @END_DATE))
+ ' days '
+ CONVERT(varchar(6), (DATEDIFF(second, @START_DATE, @END_DATE)/ 3600) % 24)
+ ' hours '
+ RIGHT('0' + CONVERT(varchar(2), (DATEDIFF(second, @START_DATE, @END_DATE) % 3600) / 60), 2)
+ ' minutes ago'

else

  CONVERT(varchar(6), DATEDIFF(day, @END_DATE, @START_DATE))
+ ' days '
+ CONVERT(varchar(6), (DATEDIFF(second, @END_DATE, @START_DATE)/ 3600) % 24)
+ ' hours '
+ RIGHT('0' + CONVERT(varchar(2), (DATEDIFF(second, @END_DATE, @START_DATE) % 3600) / 60), 2)
+ ' minutes to go'

end

 AS 'time string'
