Is there any way to have time constant in an Org spreadsheet formula? For example, i would like to have something like this:


to calculate how much longer I've been at work than I have to be :) The @>$5 is the total sum of hours I've been at work and @2..@-1 are the rows with days I've been working.

    “to calculate how much longer i've been at work than i have to be” while this doesn’t answer the question, the best way to achieve this goal might be to use org-clock-in.

Org mode formulas use Calc mode under the covers and Calc has a format for specifying hours, minutes and seconds. See the Emacs manual.

You can therefore use 8@ to specify 8 hours, 0 minutes and 0 seconds.

I found that to get it to work I had to calculate the vcount first. So something like this:

@>$3=vcount(@2..@-1) * (@>$5-8@)
  • this doesn't work for me at all :( i get this result: pastebin.com/eBe6nuqT

  • I'm not sure exactly what you're trying to do since in your paste vcount(@2..@-1) returns 1 and @>$5 is an empty/blank field. So the formula results in 1 * (0 - 8 hours). The result shown in @>$3 is quite correctly -8@ 0' 0." i.e. -8 hours, 0 minutes and 0 seconds. See pastebin.com/Xzam2S8m where I have changed your time format to the calc format, summed it up into @>$5 and subtrated 8 hours from it. (vcount(@2..@-1) is still returning 1 though).

  • thanks, this works if you don't use HH:MM:SS format, which is fine for my case
