If you are on CF7, you can use cfform/cfinput to make sure they are entering a valid time value.
<cfform> <cfinput name="timefield1" required="yes" validate="time" message="You must enter a time in format hh:mm:ss"> <cfinput name="timefield2" required="yes" validate="time" message="You must enter a time in format hh:mm:ss"> </cfform> Then... <cfoutput>#DateDiff(form.timefield1,form.timefield2, [precision])#</cfoutput> Note that DateDiff returns a date/time value rather than an integer value, this threw me off for a while recently. -- Josh ----- Original Message ----- From: "Eric Lackey" <[EMAIL PROTECTED]> To: "CF-Talk" <[email protected]> Sent: Monday, February 27, 2006 10:39 AM Subject: RE: Time Calculations > As long as it's a valid date/time object, ColdFusion can give you the > difference. > > <cfset dteThen = "2005-12-01 12:30:00"/> > <cfoutput> > The number of seconds since then is #DateDiff('s',now(),dteThen)# > </cfoutput> > > > -----Original Message----- > From: Love Sponge [mailto:[EMAIL PROTECTED] > Sent: Monday, February 27, 2006 11:37 AM > To: CF-Talk > Subject: Re: Time Calculations > > I know DateDiff would work in many cases but here the user is inputting > the time.
