this is a toughy...

so when ever the sproc runs on user submit...it takes the current date - whatever go_hour is set to...
-----------
if the user presses button at 9:30PM...and go_hour is '1:00 AM' then
@countdown = '2:30'

as it will be 2 and half hours till process runs as scheduled at 1:00AM...
-----------
if the user presses button at 11:45AM...and go_hour is '2:00 PM' then
@countdown = '2:15'

as it will be 2 hours and fifteen minutes till process runs as scheduled at  '2:00 PM' ...
-----------

Just use date types

declare  @GO_HOUR  nvarchar(10)
Set @GO_HOUR  = '1:00 AM'

DECLARE @CURR_DATE smalldatetime
SET @CURR_DATE = ISNULL(@CURR_DATE, getDATE())

declare @countdown nvarchar(10)
set @countdown = convert(varchar(8),
    convert(datetime,@GO_HOUR)
   -
    dateadd(d,-datediff(d,0,@CURR_DATE),@CURR_DATE),8)

select @countdown
