Make writing of the out/ directory from the status/ directory deterministic

#13600 (moved) introduced three new execution modes with a separate mode for writing files in the out/ directory. However, a newly written out/ directory may differ from a previous out/ directory even if the status/ directory has not changed. The main (or only?) reason is that documents containing graphs only contain the past 3 days, 1 week, etc. of data ending at the current system time when writing documents. We could change that and write the last known 3 days, 1 week, etc. of data to make the process of writing the out/ directory from data in the status/ directory more deterministic. We should try changing that to see if there are other differences. If it's easy, let's do it.
