Why is relative time is search not working?

[jip31]

hi

I use this relative time in my search

earliest=@d+7h latest=@d+19h 

 now I want the same slot time but one day ago (it means between 7h and 19h)

so i am doing this but it doenst works

earliest=-1d+7h latest=-1d+19h 

what is wrong please?

Keep in mind that =@d is a short way of expressing =-0d@d. As best practice, I recommend you use =-0d@d. 

earliest=-1d@d+7h latest=-1d@d+19h
