Re: How do I convert a hex date?

<cfset newDateTime = dateadd("n",numberOfWholeMinutes,"01/01/1601 12:00 AM")>

The 3rd argument of the dateAdd function should be a datetime object. So you could improve it with something like this

<cfset newDateTime = dateadd("n",numberOfWholeMinutes,createdatetime(1601,1,1,0,0,0))>
