Also the data acquisition software. I have written a few data
acquisition programs and in some cases the sample rate was extremely
high over an extended period of time. To keep the file sizes down to
something reasonable I stored the captured data with a compression
algorithm which, amongst other things, eliminated most of the time
stamps. I then provided an user option in the UI to either
display/export the raw data or a representation of the full details.

What the OP describes is simple raw data and maybe there is a similar
display/export option in the capture software being used here.

It might also be helpful if you mentioned your data acquisition hardware.

It might be that using a standard interval reading is possible and you
don't have to guess about the readings at all.

Start 00:00:00, first interval 00:01:00, second interval 00:02:00 etc...

It might be helpful if you post the actual start/stop times for the
2026 samples. There's more than one way to skin this cat and I'd only
look for solutions outside of Calc as a very last resort.

Thanks for the replies.

                                           My earlier example was a
simplified version of the data I'm working with. When Brian & Wdragos
technique is applied to the 2026 samples I really have, it sort of
works so
I can see what your talking about. I keep altering the incrementation
takes place in this technique to try to get the last cell to say the
time.  It comes pretty close but is always off by a few minutes. The
for this is theres a limit to the precision you can do with Times in
OpenOffice Calc. Using the hr/mn/sec format you can't generate small
increments to get the generated times to match the stop time. If
there was a
hr/mn/sec/fraction of a second format you could do it. In Calc theres  a
time format that looks like this, but in practice it doesn't 'roll over'
like say minutes or seconds.

It looks like Calc's stock functions won't do the job. I'm thinking of
getting around this by finding some source for a stopwatch program, and
maybe modifiying it to do something similar, but with a greater
precision of
