Thanks for the quick reply David.

What I need is a simple conversion that can say 80000=08:00, 94500=09:45 and
100000=10:00 and so on.
I agree with you that the extra leading "0s" would need an extra check.

The data situation is the following: I have several thousands of
observations  each day and I want to average them out throughout bins of a
specified size (either 15 or 5 minutes). An example of the data follows,
where the first column is the time and the second represents seconds between
different events.
