I've analyzed the output from the bindings command
'Dvr/GetUpcomingList'.
- First you are using the recording start/end times
  (['Recording']['StartTs']/['Recording']['EndTs']), not the programme
  start/end times (['StartTime']/['EndTime']). So they are with the
  pre- and post-roll included.
- Secondly those timings are all rounded to 5 minutes and thus
  inaccurate.
- Thirdly I now realize that these do not include any follow-up jobs,
  so the backend could be active longer. This is not a real problem as
  a job is not time bound and would simply continue after a resume,
  but it's neater to take these into account.

Is there a command to check the job-queue? And one to check on
current activity? The latter could be used to postpone a suspend.
Could there be a subcommand to not round the timings?
