Time Format in DataGrid Problem

I am using VB6 and Microsoft Access and got the following problem:

I populate a DataGrid with a SQL statement as follows:

Adodc1.RecordSource = "SELECT MonthOfYear AS Month, SUM(Time) AS [Total Time] FROM Table GROUP BY MonthOfYear"

When the statement execute for ex: 13:00:00 + 13:00:00 it gives an answer of 1.08333 which is correct. My problem is when I add the following statement.

DataGrid.Columns(1).NumberFormat = "hh:mm:ss"

It converts the answer to 02:00:00 but I want the answer to be displayed as 26:00:00 any suggestion would be appreciated to stop the formatting part from discards the whole day part.

Thanks
