140370 - no subject - I have a task report where i need to cap

I have a task report where i need to capture the tasks 12 PM today or earlier day. I am not sure which function needs to apply for calculating 12 PM. Applying the below function returning the yesterday's tasks.
{field:"8",operator:"LESS_THAN",value:today()-1}
Thanks in advance.
