I discovered the other day an interesting tid-bit in cf 8 when comparing two date strings that were set as the following:

<cfset date1 = '5/19/2010' />
<cfset date2 = '19/5/2010' />
<cfif date1 eq date2>the same<cfelse>different</cfif>

When doing so the strings are considered equal. I gather this is because it translates both strings as dates automatically but one is in d/m/yyyy format and the other is m/d/yyyyy format. This was troublesome for me since I was comparing two dates that come from a possible user input, entering them into a text field of a form as an alternative to using the date picker.

DateCompare() results the same. In order to solve my issue without creating a brand new date using createDate(), I was able to use the compare() function as in the following:

<cfif compare(date1,date2) eq 0>the same<cfelse>different</cfif>

Strange thing about cf but not really a bug.
