[libreoffice-users] time and date difference

2015-04-24 Thread sserra
hello everyone,
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 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

then for the hours

G14 = 15:30
G15 = 16:20
G16 = (G15G14)+G15-G16 (as suggested by the wiki:
https://help.libreoffice.org/Calc/Calculating_Time_Differences)

but again I have a value error..

does anyone knows how can I solve this??

This should work (if your date locale is set appropriately) if these 
are genuine date values, i.e. numbers formatted as DD/MM/ 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 = (G15G14)+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
=(G15G14)+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.

Re: [libreoffice-users] time and date difference

2015-04-24 Thread Michael D. Setzer II
Did the work below, but then came up with a simpler option.

Converts difference to minutes
=(E15-E14)/TIME(0,1,0)

Above Answer ANSWER/60
=((E15-E14)/TIME(0,1,0))/60

Above Answer  INT(ANSWER/60) gives full hours
=INT(((E15-E14)/TIME(0,1,0))/60)

Above Answer MOD(ANSWR,60) gives minutes left
=MOD(((E15-E14)/TIME(0,1,0)),60)


Original way of doing it.

E14 = 04/23/15 03:30 PM
E15 = 04/25/15 04:20 PM
E16 = 48
E17 = 50
E18 = 0
E19 = 50
E20 = 48
E21 = 48.83

Formula in E16 to calc Hours in full days
=int(e15-e14)*24

Calculates the number of minuts left
E17 = =MOD((E15-E14),1)/TIME(0,1,0)

Calculate number of Hours in partial day
E18 =  =INT(E17/60)

Calc Remain Minutes
E19 = =MOD(E17,60)

Calc Total Hours
E20 = =E16+E18

Calc Hours with fraction.
E21 = =E20+E19/60

Added 12 hours to test  results.

   04/23/15 03:30 PM


   04/26/15 04:20 AM


  48
Full Hours

 770
Extra 
Minutes

  12
Hours

  50
Minutes

  60
Total 
Hours

   60.83

Why? 4.3.6 is latest 4.3.x series...

It never amazes me the number of people who chase bugs using a dated
release - especially when it is the very first release in a major new
series...
