If Statment ( [DateTime in a Sharepoint Column] = Now (), Yes,No )

Curious to know if this is possible, i wish to create an if statment in a sharepoint calculated column where if the date in that row is equal to the time now than mark the column as yes.

The datetime column is called OvertimeDateTime,

This is what i would have normally written anywhere else right?


Anyhelp would be ballsriffric

Seriously thanks though, i cant figure it out.
