Help! Parameter Conversion Unix Time

My dates are in unix time and the paramaters are entered as 7/6/2004. How can I convert the date in the parameter field back into unix time so it will retireve the records.
Unix time is the number of seconds from 1/1/1970 at 12:00am
ThanksFor a variable dateTime of type DateTime you can use the follwing
expression:
dateTime.Subtract(new DateTime(1970, 1, 1)).TotalSeconds
This returns floating point value and may contain fractions of a second.
