I have a SQL table, named Booking, with a field named START that contains the date and time in the form of "yyyy/mm/dd hh:mm:ss".
I can compare that value to the current date and time using "WHERE GETDATE() < Booking.Start" as part of the query
What I actually want is to subtract 4 minutes from GETDATE() while maintaining the date part and compare against the Booking.Start field.
