datatoolcan ignore invalid choices automatically upon job submission.

Values of the Temporal extent column are the limits for
--start-date and --end-date options with the main
datatool script.
Note
CanESM5 model reports all variables at the beginning of
the hour (YYYY-mm-ddTHH:00:00).
Note
MPI-ESM1-2-LR and CNRM-ESM2-1 report pr, rlds,
rsds at the middle of the hour (YYYY-mm-ddTHH:30:00), while
all other variables are reported at the top of the hour.
