More problems with revExecuteSQL

I believe that even with variable substitution, you have to put ' around 
any non-numeric parameter.  Your SQL statement doesn't have that.  The 
13T01 is the time.  It appears that the expression for the date is 
getting evaluated as a math function.

I think your template SQL statement should be something like:

... VALUES (':1',':2',...

Hope that helps
