Not trying to correct Tamar's reply (wouldn't dare!) but that would be

REPLACE e WITH e + (i - DTOT(TTOD(i)))

Now, if this data comes from the same Excel file that you mentioned in a recent thread, and if your Excel columns register separately the date and the time of an event, and if you're interested only in the final datetime representation of the event, you can calculate the value without going through this intermediary step, by adding the involved columns at front (if you're getting a column value of 30/12/1899 14:31:00, it's probably because you're transforming a time Excel value into a VFP datetime value).

Hope that this makes sense...
