How do I format date and time on ssrs report?

on SSRS report I need to show todays date and current time

i tried this =FormatDateTime(Now,"MM/dd/yyyy hh:mm tt") but this is not working for me giving an error.

Anyone please help me for expression ?

I want output display like 4/12/2013 12:05 PM

Solution 1:

=Format(Now(), "MM/dd/yyyy hh:mm tt")

Output:

04/12/2013 05:09 PM

Solution 2:

If the date and time is in its own cell (aka textbox), then you should look at applying the format to the entire textbox. This will create cleaner exports to other formats; in particular, the value will export as a datetime value to Excel instead of a string.

Use the properties pane or dialog to set the format for the textbox to "MM/dd/yyyy hh:mm tt"

I would only use Ian's answer if the datetime is being concatenated with another string.
