I am using LibreOffice Version: 4.3.0.4 and I am having issues
calculating time differences. I would like to calculate the time
difference in hours between the following
date/times:
E14 = 23/04/2015 15:30
E15 = 25/04/2015 16:20
E16 = DAYS(E15;E14)
But I get a value error ...
This should work (if your date locale is set appropriately) if these
are genuine date values, i.e. numbers formatted as "DD/MM/YYYY HH:MM"
- but not if the cell contents are text values.
so I split data:
F14 = 23/04/2015
F15 = 25/04/2015
F16 = DAYS(F15;F14) ---> Ok, I get 2, multiply x 24 = 48h and it's fine
This mean that you *do* now have these values as genuine dates, not text.
then for the hours
G14 = 15:30
G15 = 16:20
G16 = (G15<G14)+G15-G16 (as suggested by the wiki:
https://help.libreoffice.org/Calc/Calculating_Time_Differences)
but again I have a value error..
If you really have put a formula including G16 into G16, then you
have a circular reference, and you may see Error 522.
does anyone knows how can I solve this??
If you use
=(G15<G14)+G15-G14
it should work (whether you have times or text).
It's important to understand the effect of cell formatting in
spreadsheets. When you type something into a cell, the value may be
converted and the cell formatting may be changed. Such changes may
not be immediately evident, but you need to appreciate them if you
are to see why formulae work or don't work. There are two facilities
that may help:
o Unless you have specifically set cell alignment, text values will
be left-aligned and numbers (including date/times) will be right-aligned.
o Go to View | Value Highlighting (or Ctrl+F8). Text values show in
black and numbers (including date/times) in blue.
I trust this helps.
