All, I notice that in a table, I can use active timestamps, do arithmetic with them, and get meaningful results. However, if I use inactive timestamps, I get different results. I prefer the way active timestamps work, since I can easily do date arithmetic with them.
The problem with active timestamps is that they pollute the agenda. Imagine a table with 100 rows of timestammps, all the same date. * Tables with dates ** Active timestamps | Begin | End | Days | |------------------------+------------------------+----------| | <2012-09-24 Mon> | <2012-09-25 Tue> | 1 | | <2012-09-25 Tue 17:50> | <2012-09-25 Tue 19:37> | 0.074305 | #+TBLFM: $3=@$2-@$1 ** Inactive timestamps | Begin | End | Days | |------------------------+------------------------+------------------| | [2012-09-24 Mon] | [2012-09-25 Tue] | [-1, Tue - Mon] | | [2012-09-25 Tue 17:50] | [2012-09-25 Tue 19:37] | [0, 0, 321:1850] | #+TBLFM: $3=@$2-@$1 It seems to me that they ought to behave the same, but I would normally want inactiv timestamps when doing calculations.
