Would something like this work?

Subject: Use sql to calculate a time difference between 2 records
Afternoon everyone
I have a non-keyed file that is in chronological order. The record
contains a timestamp field.
How can I use SQL to determine the time difference (in seconds and parts
of
seconds) between one record and the next
As always any responses are MUCH appreciated
Thanks in advance
