query.cfc exception when using time mask

... thinks it's a bound parameter:

```
select 
 sessionId
 , title
 , descr
 , byline
 , location
 , startTime
 , endTime
 , sortVal
 , (SELECT CONVERT(VARCHAR(11), startTime, 106) AS [DD MON YYYY]) as datepart
 , (SELECT CONVERT(VARCHAR(11), endTime, 108) AS [hh:mi]) as timepart
 from tblSession
 order by startTime, sortVal
```
