Thanks for your help with this, BKBK. I have been working on it for a day, and discovered some useful info and eventually found an easier way to accomplish this.
Below you will see the number of ticks can actually be retrieved by using the Java parseLong() method. I have no idea what's up with inputBaseN or why it's not working for this scenario, but we can forget that for now. Also, I discovered the Windows system time does not start at 1600, it starts at 1601. The guy in the article I linked to actually got it wrong, so apologies for any confusion about that! Finally, I convert the date to local time.
Below is the full code to convert the SharePoint hex date to regular date using ColdFusion. Hope this helps someone else in a similar situation.
<cfset hexdate = #Replace(meta.vti_imgdate, "0x", "", "All")#> <cfset hexdate2 = #Replace(hexdate, "|", "", "All")#> <cfset str = "#trim(hexdate2)#"> <cfset numberOfTicks = createObject("java", "java.lang.Long").parseLong( str, 16 )> <!--- By definition, 1 second = 10,000,000 ticks but need to divide by 60 and call it minutes or number will be out of range for ColdFusion. ---> <cfset numberOfWholeMinutes = round(numberOfTicks/(10000000*60))> <!--- Starting datetime is 1st January 1601, which is the Win32 epoch time ---> <cfset newDateTime = dateadd("n",numberOfWholeMinutes,"01/01/1601 12:00 AM")> <cfset newDateTimeUTC = DateFormat(DateConvert("utc2Local",newDateTime), "mmmm dd, yyyy")>
By the way, here is a cool article about a guy that goes into something similar: http://ruthsarian.wordpress.com/category/programming/coldfusion/
