Try this:

SQL

UPDATE
   Yourtable
SET
   datetimecol = DATEADD(day, DATEDIFF(day, datetimecol, getdate()), datetimecol)

Let say the new date is current date using getdate()
we can do this to get the date part:

convert(varchar, getdate(), 101)

we can also do this to get the time part of the old date time:

convert(varchar, datetimefield, 114)

So the idea is to concatenate the date part of a new date time with the time part of the old date time:

SQL

update table1 set datetimefield =
(convert(varchar, getdate(), 101) + ' ' + convert(varchar, datetimefield, 114))

As for the meanings of 101 and 104, refer this for more detail:
