How to input a variation of datenum(now)?

I am trying to create a variation of the datenum(now) command with a twist, the code must output the time as if I typed it at 7am.

I am proceding the following way,

 datestr(round(datenum(now)), 'ddd dd/mmm HH:MM PM ')

with output

 ans =

 Thu 11/Oct 12:00  AM

I want a variation of this code that outputs the folliowing for whenever I type it

 ans =

 Thu 11/Oct 7:00  AM

Output the current day and month of the input, but the time must always be 7am of the current day

Can you please help?

Hint:

    datestr( floor(now) +7/24, 'yyy-mm-dd HH:HH:SS' )

returns

    ans =
