Re: [libreoffice-users] Re: Generate a column of times

This is what Brian is trying to explain...

You've got 6 samples. The first one taken at 12:04PM, the 
last one at 12:36PM.

The total elapsed time is 12:36PM - 12:04PM = 22 minutes.

22 divided by 5 (always the total number of readings minus 
1) = 6.4 minutes or 6m and 24s per interval.

Adding 6:24 to 12:04PM gives you the time of the second 
reading, 12:10:24PM. Enter that value into cell B2.

Now we make the computer do the work for all remaining 
readings. Follow these instructions carefully:

Highlight cells B1 and B2. Hover the mouse over the little 
black square in the lower right hand corner of the the 
highlighted cells until it turns into a cross (+). Now hold 
the left mouse button down and drag the mouse downward. As 
you drag the mouse each cell will fill with the correct time 
stamp.

You will end up with this:

12.7   12:04:00 PM
8.9    12:10:24 PM
3.5    12:16:48 PM
2.1    12:23:12 PM
7.2    12:29:36 PM
6.1    12:36:00 PM


If you want to use 1S as your interval the just enter 
12:04:01PM in B2 and drag the mouse as explained above.

Hope that helps...

-Bill
