I would like to measure the date/time difference from the "Open Time" to the "Resolve Time" and put the data in a new column(Mean Date/Time To Resolve).

As you can see some of the records have days bewteen them.

 

[lbass]

Create a formula like this {@mins}:

datediff("n",{table.opentime},{table.resolvetime})

This will return the difference in minutes. You can convert the result to a string representing days, hours, minutes by using faq767-3543.

You didn't explain the "mean". If you need the average across all records, then insert an average on {@mins} and then use the faq to convert the results.
