Complex filter in TCC to filter out candidate who has a latest CSW date of less than 24 hours

Can anyone guide me in this requirement please: Complex filter in TCC to filter out candidate who has a latest CSW date of less than 24 hours

I have a XML but it is not working as expected, pleas correct my XMl:

<quer:field path="CSWLatestDate"/>
quer:add
<quer:date type="now"/>
-1</quer:integer>
</quer:add>
</quer:lessThanOrEqual>quer:lessThanOrEqualquer:integer

Will it work if we change it to:

<quer:field path="CSWLatestDate"/>
quer:add
<quer:date type="now"/>
-24</quer:integer>
</quer:add>
</quer:lessThanOrEqual>quer:lessThanOrEqualquer:integer

Instead of 1 if we subtract 24 will it work?
