Another trick and tip to my blog!
If you want to show the parameters with data and time option
both below is a quick way to do it.
Normally date/time parameters only display the date however
if you add below expression now() then the parameter value shows current date
and time.
If you want one date/time parameter to show a day before
current date then use DateAdd option as below.
=DateAdd("d",-1,Now())
When you run the report final result will look like below.
