Firstly are you sure you are looking in the correct place or atthe right thing?
You have recovered a field from your qvd file and called this MAXCRTTIME. You then have created a variable with the same name MAXCRTTIME.
You now have one field and one variable. The same name but two different elements in your qvw.
If you open a list box and display the field you will see 40672,803 which looks like a timestamp displayed as a number, if displayed as a timestamp this would show 2011/05/09 19:16:19.
If you create a text box and put inside it =MAXCRTTIME (this is the variable) you will see 201105.
Maybe this is your problem, in which case you don't have one.
I thought there may be an issue of different settings between the server and your workstation but can't see one.
Hope this helps
