ColdFusion date subtraction

I am converting a ColdFusion application to .NET, and I have a question about date subtraction.

In the following if statement, qTripID.etd is the utc date and time of a flight departure, the comment says that that it is testing whether the flight has already departed.

<cfif qTripID.etd - DateConvert("local2utc",Now()) LT 0.166666666666667>

What type of information does the expression above return?

minutes? days? hours?

The entire expression:

qTripID.etd - DateConvert("local2utc",Now()) LT 0.166666666666667

returns a boolean value: 'LT' is ColdFusion's 'less than' operator.

I think you're asking what units is the 0.166666666667? In which case it is days - the 0.1666... value being 4 hours.
